See the invisible! Seek Thermal - Santa Barbara Thermal Imager
When I was small, magnesium for various interesting experiments was wheeled off iron wheels from the wheels of an airplane dumping aircraft. Now, magnesium is used to make housings for household appliances, one of which is described in a short review.
The imager ...
There are bad people who use it from birth. The thermal imager is unavailable to most normal people because of the enormous price, although there are only ones who were able in 2013 to make the device on their own for “ ... for less than $ 100 ”. It is not known how many people gathered it, but at least more than one hundred thousand read the article on Habré. There are many people who want to own a thermal imager, and one way is to buy its main element at a cheap priceand then (2014 story) equip with “brains” (Arduino, STM32 or Raspberry PI). The method is interesting, but a screen is still needed for the brains, and not everyone is a radio amateur.
Thermal imagers are mainly acquired by reputable enterprises and organizations for various kinds of thermal imaging surveys with the ultimate goal of making money. Customers in such studies identify violations during the construction and operation of various systems, which, when eliminated (violations), saves energy and, ultimately, financial resources.
Many people want to have a thermal imager, but at the same time, some already know why, while others just want to, without thinking about its application. The cost of the device makes the circle of owners narrow enough, crowding out dreamers beyond it.
And slowly, slowly, the price of this device began to decline, which significantly expands the number of its potential owners.
A thermal imager with acceptable parameters has become more accessible (characteristics-price-quality), and it is time to think about purchasing it for your household.
For those who just want and have not yet decided on its application, a little work is proposed under the code name “Thermal imager - a blue childhood dream” or “Dreams come true not only at Gazprom!”
A person lives in his house, spends considerable money on heating, feeling some discomfort, but doesn’t know what to do, maybe the stove / boiler is working poorly, maybe the windows of the wrong system, maybe the batteries are not modern, but maybe warm floor?
Меняются котел, окна, батареи, появляется теплый пол..., но ситуация улучшается незначительно.
А всего лишь одна фотография могла бы направить его деятельность в совершенно другое русло.
Купил хозяин этот дом, или сотворил его сам — это науке неизвестно, но известно то, что в те годы, когда он был построен, не было возможности сделать такую фотографию или заказать её редким владельцам тепловизоров.
С виду, это обычный кирпичный дом, но стоит посмотреть на него в другом диапазоне волн, как взору открывается красивая, но совсем не радующая с точки зрения тепловых потерь глаз картина.
Последствия некоторых ошибок строительства, примеры которых будут приведены в статье, можно уменьшить, но для начала, их необходимо обнаружить, в чем нам поможет тепловизор «Seek Thermal”.
Its scope is not limited to construction. The operation of buildings, the adjustment of thermal equipment, electrics and electronics, medicine, hunting, the search for missing people, security and other useful, comic-entertaining and research applications, some of which will be demonstrated in this article.
Find a black cat in a dark room, especially if she is there!
I will not devote a place in the article to beautiful factory packaging with a magnetic latch, a dustproof and moisture-proof box for storage and carrying, views from all sides - all this can be seen in the album “ Thermal Imager“ Seek Thermal ”, a link to which will be duplicated at the end of the article.
In the carrying box, the thermal imager almost merges with the keys in the bundle.
The device uses modular technology when, in order to reduce the cost of the product, part of its functions is assigned to another device.
A smartphone is used as the main computer (essentially a computer), a screen and a place to store images.
The lens, IR sensor, controller for signal preprocessing and a connector for connecting to a smartphone are located in a separate magnesium housing. The device has an individual serial number located next to the connector.
The first sensation when you see this thermal imager is that it is unrealistically small! And how did you manage to accommodate such opportunities in a case commensurate with a match?
For example, SmartScope and Red Pitaya oscilloscopes work in a similar modular fashion.
This approach allows you to create a measuring complex (module and smartphone), which has high characteristics at an affordable price. In addition, the efficiency of using the telephone jack is increased :)
Features of the “Seek Thermal” thermal imager.
The image invisible to us enters the device through a chalcogenide lens with an angle of view of 36 degrees. The lens has a focus ring.
The sensitive element is a sensor consisting of a matrix of microbolometers based on vanadium oxide (VOx), operating in the electromagnetic wave range of 7.2 ... 13 microns.
The matrix has 206x156 sensitive elements - a total of 32,136 pixels in 12 microns. For a thermal imager, this is a good indicator.
The shooting frequency is 9 Hz.
Although after a review of the pyrometer, which is essentially a thermal imager with one sensitive element, the number of pixels in the matrix is impressive, but all the laws described in that article are also inherent in the thermal imager. This applies to the surface emissivity, the accuracy of temperature determination and other parameters. Therefore, an important property of the thermal imager is not so much the ability to determine a specific temperature from the working range of -40 ... +330 degrees Celsius, but the instant availability of the thermal picture of the object for analysis of its operation.
Miniaturization with increased capabilities.
The technology for the production of IR matrices is quite complicated (China has not seem to have mastered it yet), so there are only a small number of their manufacturers. The headquarters of the thermal imager manufacturer “Seek Thermal” is located in Santa Barbara, California, USA.
The thermal imaging camera is connected to the connector of the device running on the IOS or Android operating system. Each system has its own version of the thermal imager.
A list of supported devices is available on the “Instructions and Software” tab in the “User Guide”.
An Android device must have version 4.3 or higher, and also support USB OTG mode.
It’s quite simple to check the support - during the installation of the “Seek Thermal” application from Google Play or iTunes, a message appears on the screen that the device is not supported.
The list of supported platforms does not please owners of Windows phones, so I had a small problem ...
Взятый на пробу “Lenovo A2010” с Android 5.0 Lollipop совсем не ругаясь, позволил установить приложение Seek Thermal, но при подключении тепловизора, приложение упорно просило подключить устройство, и не выводило изображение с камеры на экран телефона. По всей видимости, в смартфоне не реализован режим USB OTG.
Попытка номер 2. Друг, который обнаружил незначительный дефект в одной из серий HDD Seagate, предложил на тестирование свой планшет “Cube i6” с двумя операционными системами, одной из которых был Android 4.4. Ожидания нас не обманули – данный планшет можно внести в список поддерживаемых устройств.
Большой экран позволяет комфортно рассматривать изображение и придает солидность тепловизионному комплексу.
Due to the different orientation of the connector, on some models of Android devices, a situation may arise when the camera will not look forward, but at its owner. This is exactly what happened with the tablet.
It is possible that a thermal selfie will also become popular, but in this case, you still need to turn the thermal imaging camera in the other direction. I rescued the MicroUSB cable from the package.
If the manufacturer adds the MicroUSB “flip” to the Android kit in the form of a simple adapter, then it will be great, since the MicroUSB cable is 1 meter long, which is inconvenient on the one hand, because it hangs and clings, but on the other ...
A man who has buried himself on the screen is a familiar element of the landscape, but imagine a picture when he walks with a 9.7-inch phone or tablet (my case), taking pictures of all kinds of different things. It will immediately attract attention, which is sometimes not necessary at all. Another thing is cable. It allows you to rotate the tablet horizontally or conveniently placed on your lap in the car, which immediately turns the thermal imager into an unremarkable resident.
The thermal imager on the cable is tiny and almost invisible. The small weight of the camera (one and a half dozen grams) is not felt at all, which allows you to take a long shot without voltage by pressing a button on the application screen when an interesting frame appears.
A few words about the program.
The “Seek Thermal" application is installed from Google Play and iTunes.
A picture taken from iTunes shows the main elements of the program.
Menu:
- help;
- the choice of the unit of temperature (Celsius, Kelvin);
- color palette (color selection to indicate the hottest area: black, white and several color options);
- image settings (aspect ratio 4: 3 or 16: 9 for different smartphone models, watermark (date and time, location, Seek logo), disabling geo-data, image smoothing);
- terms used (Internet required);
- assistance to developers (sending usage data);
- about the thermal imager (for the device under test: application version 1.9.3, camera type UW-AAA, camera number 121110QA872, camera application version 1.3.0.0., Image processing program version 2.2.0.0.);
Thermal Plus:
- enable / disable the smartphone’s camera to view the visible image together and infrared.
Seek Thermal Community (Seek Thermal Community).
Gallery (image gallery):
- work with captured images (viewing, deleting, sending).
Camera type and shutter (camera and shutter type):
- selection of the operating mode (photo or video) and the button to take a picture or start recording video.
Mode (thermal imaging display mode):
- output of a simple picture of a thermal image with a selected palette;
- digital temperature indicator at the center point of the frame;
- digital indicators of maximum and minimum temperatures with an indication of their location in the frame;
- an adjustable area when an area is displayed in which the temperature is greater, less than or equal to the selected value. This mode is useful, for example, for detecting people with high fever.
Recognition of objects.
The thermal imager operates in the infrared wavelength range, so the observed picture is different from the usual frame taken by the smartphone’s camera. There is a problem of “geo-referencing” in the frame of a thermal imaging image.
For identification, a thermal imager is taken and a classic picture is taken in the visible wavelength range, combining these images. Since “Seek Thermal” itself works only in the infrared range, a normal picture is taken by the smartphone’s camera - the program has the ability to display both a regular and an infrared image on the screen. At the same time, the lenses of the camera and the thermal imager are slightly spaced, which leads to a discrepancy in the images. Using a USB cable allows you to install the thermal imager as close to the smartphone’s camera as possible.
To accurately determine an interesting site, you can use the simple “heat label” method. The assistant moves his finger perfectly visible on the screen of the imager across the real terrain, which allows you to quickly point to the desired object.
Speaking of fingers and other parts of the body.
Some people get their fingers freezing constantly. On the thermal imager’s screen, the hands of the hot guy and the frozen look like this.
The thermal imager can be used to study a person.
In addition to cold fingers, ears, or “burning” eyes, on the screen you can observe the flow of cold air when inhaling. The alternation of warm (exhale) and cold (inhale) air is shown in the horror film “ Nose ”. Thus, it is possible to discreetly and at a distance determine - can a person breathe indifferently? Just in this case, it is better to use a cable.
The sensitivity of the device allows you to detect temperature differences in different, seemingly homogeneous parts of the body. For example, a thermal imager shows large veins located close to the surface of the skin.
Thermal imaging has long been used in medicine, but to make it achievable at home!
This is the leg of the one who needs the leg!
Due to the large number of sensor matrix elements, many people in thermal images are easily recognizable.
Some photos resemble the works of famous avant-garde artists. What is not Vasily Kandinsky?
Or this “Lady with a Dog”?
“Seek Thermal” allows you to study the device of various devices, “looking” inside an opaque case.
In the infrared range, a seemingly homogeneous plastic case of a hot water storage heater is observed with giblets. It turns out there are two tanks!
It is believed that the most dusty place in the house is the back of the refrigerator, because hot air circulating as a result of the cooling radiator contributes to the deposition of dust on it. If you consider that the refrigerator moves away from the wall only during repairs in the room, then the efficiency of the compressor decreases slightly, with a simultaneous increase in the electricity bill.
In this regard, in modern models, the cooling radiator is installed inside the side walls of the refrigerator, which on the outside represent a flat surface. But the thermal imager allows you to see its device.
In addition to studying the design of the refrigerator, the thermal imager helps save energy.
As a result of leaks in the door, the refrigerator cools not only the products inside, but the room, while consuming an increased amount of electricity and bringing the repair time closer. The gap in the seal is clearly visible on the screen, where the place of money leaking is shown in dark color (the usual photo of this refrigerator for us is in the album).
I always thought that the sole of the iron was warmed up evenly ...
The process of ironing clothes in the thermal range looks quite interesting.
Anyway, it’s better not to watch how the gas burner works, otherwise it will be scary to approach it.
The film "Burning gas (hot air) on the gas panel . "
Night shooting and the problem of excess weight.
The photographer always thinks about the necessary amount of light to get a high-quality image when taking photos / videos. The thermal imager breaks this stereotype - you can shoot with it at any time of the day, or even at night, which is very unusual.
There is no need for a flash or other illumination. All warm bodies perfectly contrast with a less heated background and are visible in absolute darkness. The thermal imager emits nothing, unlike For example, from a camera with IR illumination.
Observing people in the thermal imager, two main directions of energy consumption are immediately visible - maintaining body temperature (a person always radiates thermal energy) and movement. Therefore, overweight people have to consume more food in order to spend more energy.
Lost.
The thermal imager can be used to search for lost people, which will make it possible to detect them faster, since the method works even at night, when the classical methods are practically powerless.
Sometimes people are “lost" consciously. When searching for “losers” in paintball or while guarding objects, the thermal imager will give some advantage.
The thermal imager was not tested during the hunt, but city cats and dogs can be seen quite well. A flock of mongrels was observed from a distance of 120 meters, then they fled behind the house.
City hunting trophies in conditions of “exposure” to surrounding heat sources: A
running cat , playing the role of a hare.
Small dog depicting a fox.
Transport.
On the screen of the thermal imager, the diesel locomotive shines beautifully, because in its name there is the word “heat”.
Unlike the Lumiere brothers film, thermal shot of the train allows you to determine overheated axle boxes on the go. By the way, sound is not recorded during video recording, therefore, when watching a movie, you have to say it yourself: “Tukh-tukh-tukh-tukh ...”.
After the train, the picture that the infrared guidance head sees when flying to the plane is easily imagined.
Beautifully “burning” cars. Wheels, engine compartment, interior and silencer are the source of bright parts of the frame. On the roadbed there is a reflection of the muffler, which beautifully illuminates the bottom of the car.
In addition to asphalt, the reflection of heated objects was also seen on glass, ceramic tile, galvanized fence.
Rims, a silencer and an engine compartment are mobile “IR heaters” of the roadway.
After arriving at the parking lot, the car still pleases the thermal imager with its bright light for a very long time, therefore this fact can be used to detect cars that have been parked / stopped for a long time.
Now it’s clear why cats like to lie on the hood or under the car so much?
As with finding hot boxes of cars, the thermal imager can easily find a car with overheated wheels in the stream, which will increase road safety.
I liked the “Kamaz”, in which exhaust gases enter the body.
A stream of cars frozen in front of a red traffic light.

Back to the survey of the home.
The house can be explored both outside and inside.
In the first case, they seek heat output (light elements on the thermal imager screen), in the second - the intake of cold (dark areas). The uniformity of radiation over the surface is also important.
One of the mistakes during construction is insufficient insulation of floor slabs or laying them so that they come close to the outer walls of the building. Since the plates are ducted, the cold air cooled at their edges circulates over the entire area, causing a cold floor problem. In the photo - heating the street with a brick house using floor slabs.
The situation is even worse when the foundation was built a little smaller. Since the floor slab has a standard size, it simply does not fit along the length, and as a result “sticks out” to the street. In addition to the installation error, in this case there will be significant heat losses.
In individual construction, channel technology for building walls is popular, when a brick wall is two planes connected across a distance by transverse bricks. The resulting voids (channels) are filled with insulating material: slag, sawdust, expanded clay, polystyrene, etc. This saves bricks, as the thickness of the walls can be reduced. The weak point of the technology in terms of heat loss is the transverse bricks through which heat loss occurs. You can calculate the area of hot spots.
The theory of open windows.
The heating temperature in apartment buildings and other houses is regulated depending on the outdoor temperature. But buildings have different thermal insulation efficiencies. In this regard, at a seemingly “legalized” temperature, in some houses it is comfortable, in others it is cold, and in the third the window panes do not close.
How to set the optimum temperature in the heating system of a particular house?
In addition to various thermal insulation of buildings, the outdoor temperature sensor, from the readings of which the temperature in the heating batteries of the ward’s house “dances”, often “shows” not what it should due to improper installation. Sometimes the system is supplemented with a control sensor in one of the apartments in order to more accurately adjust the result, but in this case there is a dependence of the heating temperature of the house on the readings of this sensor.
When examining houses with a thermal imager, it was noticed that he well defines open windows.
При помощи подсчета количества открытых окон можно повысить качество работы системы отопления дома и комфорт его жителей. Открытые окна интересуют не только домушников. Старые мастера, работающие в котельных, давно пользуются этим приемом: им достаточно одного беглого взгляда на дом, чтобы понять – холодно жителям или у них “перетоп”. Введение тепловизионной съемки дома позволит автоматизировать данный процесс.
Наблюдение за домом можно использовать для наладки гидравлического режима работы системы отопления.
Example. Often the comfort of some residents worsens due to an increase in the comfort of others (as Lomonosov said: if he arrives somewhere, then he disappears in another place). In this case, we are talking about turning the balcony into a residential area. Well, if the matter is limited only to its insulation. But sometimes the wall / window that breaks the balcony and the room breaks, and then the heating radiator is transferred to another place, with an increase in the number of sections. At the same time, the consumption of thermal energy increases and the hydraulic mode of the system changes, which negatively affects the neighbors in the risers.
The upgraded balcony is perfectly visible on the thermal imager screen. Its wall is blue / cold (insulated), and the windows burn brighter than all the neighbors.
A similar situation with garages. Heated specimens contrast with cold neighbors.
A special case of the theory of “open windows” is a cracked drive glass and a frame with slots.
When observing the house, you can clearly see the advantage of the glazing of loggias and balconies compared to cold porches with only one frame.
The thermal imager cannot peer through the window; it only displays the temperature of the glass surface. According to some reports , thermal imagers see through an opaque plastic bag. If a dress made of this material is sewn for the king, then a decent person in a thermal imager will look naked.
When examining one room, a warm rectangular spot was found on a wall about 10 cm thick made of gypsum block. The search for a heat source led to the kitchen (the other side of the wall) where the LCD TV worked. His heating was very weak to warm the wall, but nevertheless, the stain was clear. It is possible that gypsum in its characteristics is similar to the plastic bag mentioned above.
When examining heating radiators, the thermal imager allows you to see a violation of circulation when they are connected incorrectly, “clogged” or as a result of other reasons.
And here is the upper grille of the steel panel radiator.
Теплый пол повышает комфорт жителей, но его сверление для установки некоторых элементов вызывает головную боль у владельца. Повреждение трубки водяного контура или греющего электрического кабеля приводит к дорогостоящему ремонту.
Тепловизор сводит эту проблему на “нет”, так как все греющие элементы видны на экране, а метод “тепловой метки” позволяет прямо пальцем указать место, где на сверление накладывается табу.
A huge field of activity for the thermal imager opens when examining the premises from the inside. Places of heat loss are painted on the screen in dark colors. As a rule, these are door and window openings, corners of buildings, places of moisture on structural elements (which significantly increases thermal conductivity), insufficiently insulated parts of the roof, the above-mentioned elements of well masonry with transverse bricks and voids resulting from “subsidence” of thermal insulation.
With high humidity, problem areas often become a favorite mold place, but that's another story.
The device allows you to evaluate the quality of insulation, identify flaws in the construction and eliminate them, saving energy resources and money.
Such a hot handsome man spins a more heated pump for pumping water in the heating system.
An extensive scope of the thermal imager is electrical and electronics.
In the general picture, “interesting” places are marked, which are then examined in more detail upon close examination.
For example, an overheating contact and cable were detected in the driveway in a few seconds.
For electricians, the device can become pocket-sized, as Seek Thermal makes it possible to find an oxidized or loose contact in a live power assembly “on the go” and almost instantly.
When examining electronic components, the heating parts are clearly visible, but in the future you should try to cover the printed circuit board with film to reduce the effect of different emissivity of the materials used.
It will be interesting to see the battery charging by cells and banks, the effectiveness of various heat-conducting pastes when installing chipset radiators or high-power LEDs.
Did you serve in the army?
I don’t know how it is now, but nowadays, during the passage of the military commission, draftees checked flat feet, for which they moistened their feet with water or smeared with paint, then the guy stepped on a sheet, and the doctor assessed his suitability for military service using a picture on a piece of paper.
Using a thermal imager can save about a million sheets of paper annually. Save the forest - use the thermal imager!
The film " Check flat feet ".
Before shooting soap bubbles, it was assumed that the liquid of the soap solution, which has room temperature, in the process of inflation will turn into a film that quickly warms up with air, becomes bright in the picture and the ball flies up.

Traditional Review.
Disadvantages.
1. A phone is required for use, and not all phones and operating systems are supported.
2. The “reverse” orientation of the connector on some Android devices necessitates the use of a cable. A miniature “flip” adapter is required.
3. To view a normal image, the phone’s camera is used, which causes problems in combining images due to the different arrangement of lenses.
4. In the temperature value display mode, it is not possible to point the point for measurement with a finger. shows the temperature in the center of the frame, there is a dissonance between the composition of the frame and the measurement at the desired point.
5. The area where the temperature value is displayed occupies part of the frame, therefore this mode was used little when shooting - the main information is carried by the temperature change in the frame, visible by color or brightness.
Pros.
1. Miniature size and low weight.
2. Sealed box for carrying and storage, allowing you to always carry the device with you.
3. MicroUSB cable included for Android devices with “reverse” connector orientation.
4. High performance at an affordable price for many people.
Although the price still does not allow you to purchase a thermal imager as a match, a dozen surveys of neighbors' houses will make it easy and quick to recoup this device.
The availability of the thermal imager significantly increases the number of monitored objects, which means it improves the mode of their operation, reduces the loss of thermal energy.
In all previous reviews, I disassembled devices to study their design. The thermal imager will be an exception, because after two films of the electronics fan mikeselectricstuff (which is worthy of our BarsMonster ), this makes no sense.
“ Seek Thermal camera teardown part 1 ”.
“ Seek Thermal camera teardown part 2 ”.
After viewing the second part, it becomes clear that although there has been less than one thermal imager in the world, the author evokes great respect and sympathy.
About two hundred photos resulting from working with “Seek Thermal” are located in the album “ Thermal Imager“ Seek Thermal ”. For some thermal images, their analogues are shown in the usual visible range.
Thanks to the device testing program , as a result of writing reviews, I managed to become the owner of two carbon dioxide meters (parts 1 , 2 and 3 ), an infrared thermometer (parts 1 , 2 ), a Geiger key fob and a thermal imager, in connection with which I would like to wish Dadget to expand the circle sales up to cars while maintaining the conditions of this program.
The company provides a 10% discount on purchases using the DD9F2D code.
Perhaps someone will offer a professional thermal imager for testing to compare its capabilities with “Seek Thermal”. But now it’s clear that the bar for accessibility of high-quality thermal imagers has fallen dramatically and many people are able to overcome it in order to jump into the beautiful and useful world of thermal images that can improve our world or just watch it from a different point of view.
When writing an article, he “threw” a list of objects of interest for shooting. But as they say - you cannot embrace the immense!
therefore

Попытка номер 2. Друг, который обнаружил незначительный дефект в одной из серий HDD Seagate, предложил на тестирование свой планшет “Cube i6” с двумя операционными системами, одной из которых был Android 4.4. Ожидания нас не обманули – данный планшет можно внести в список поддерживаемых устройств.
Большой экран позволяет комфортно рассматривать изображение и придает солидность тепловизионному комплексу.
Due to the different orientation of the connector, on some models of Android devices, a situation may arise when the camera will not look forward, but at its owner. This is exactly what happened with the tablet.
It is possible that a thermal selfie will also become popular, but in this case, you still need to turn the thermal imaging camera in the other direction. I rescued the MicroUSB cable from the package.
If the manufacturer adds the MicroUSB “flip” to the Android kit in the form of a simple adapter, then it will be great, since the MicroUSB cable is 1 meter long, which is inconvenient on the one hand, because it hangs and clings, but on the other ...
A man who has buried himself on the screen is a familiar element of the landscape, but imagine a picture when he walks with a 9.7-inch phone or tablet (my case), taking pictures of all kinds of different things. It will immediately attract attention, which is sometimes not necessary at all. Another thing is cable. It allows you to rotate the tablet horizontally or conveniently placed on your lap in the car, which immediately turns the thermal imager into an unremarkable resident.
The thermal imager on the cable is tiny and almost invisible. The small weight of the camera (one and a half dozen grams) is not felt at all, which allows you to take a long shot without voltage by pressing a button on the application screen when an interesting frame appears.
A few words about the program.
The “Seek Thermal" application is installed from Google Play and iTunes.
A picture taken from iTunes shows the main elements of the program.
Menu:
- help;
- the choice of the unit of temperature (Celsius, Kelvin);
- color palette (color selection to indicate the hottest area: black, white and several color options);
- image settings (aspect ratio 4: 3 or 16: 9 for different smartphone models, watermark (date and time, location, Seek logo), disabling geo-data, image smoothing);
- terms used (Internet required);
- assistance to developers (sending usage data);
- about the thermal imager (for the device under test: application version 1.9.3, camera type UW-AAA, camera number 121110QA872, camera application version 1.3.0.0., Image processing program version 2.2.0.0.);
Thermal Plus:
- enable / disable the smartphone’s camera to view the visible image together and infrared.
Seek Thermal Community (Seek Thermal Community).
Gallery (image gallery):
- work with captured images (viewing, deleting, sending).
Camera type and shutter (camera and shutter type):
- selection of the operating mode (photo or video) and the button to take a picture or start recording video.
Mode (thermal imaging display mode):
- output of a simple picture of a thermal image with a selected palette;
- digital temperature indicator at the center point of the frame;
- digital indicators of maximum and minimum temperatures with an indication of their location in the frame;
- an adjustable area when an area is displayed in which the temperature is greater, less than or equal to the selected value. This mode is useful, for example, for detecting people with high fever.
Recognition of objects.
The thermal imager operates in the infrared wavelength range, so the observed picture is different from the usual frame taken by the smartphone’s camera. There is a problem of “geo-referencing” in the frame of a thermal imaging image.
For identification, a thermal imager is taken and a classic picture is taken in the visible wavelength range, combining these images. Since “Seek Thermal” itself works only in the infrared range, a normal picture is taken by the smartphone’s camera - the program has the ability to display both a regular and an infrared image on the screen. At the same time, the lenses of the camera and the thermal imager are slightly spaced, which leads to a discrepancy in the images. Using a USB cable allows you to install the thermal imager as close to the smartphone’s camera as possible.
To accurately determine an interesting site, you can use the simple “heat label” method. The assistant moves his finger perfectly visible on the screen of the imager across the real terrain, which allows you to quickly point to the desired object.
Speaking of fingers and other parts of the body.
Some people get their fingers freezing constantly. On the thermal imager’s screen, the hands of the hot guy and the frozen look like this.
The thermal imager can be used to study a person.
In addition to cold fingers, ears, or “burning” eyes, on the screen you can observe the flow of cold air when inhaling. The alternation of warm (exhale) and cold (inhale) air is shown in the horror film “ Nose ”. Thus, it is possible to discreetly and at a distance determine - can a person breathe indifferently? Just in this case, it is better to use a cable.
The sensitivity of the device allows you to detect temperature differences in different, seemingly homogeneous parts of the body. For example, a thermal imager shows large veins located close to the surface of the skin.
Thermal imaging has long been used in medicine, but to make it achievable at home!
This is the leg of the one who needs the leg!
Due to the large number of sensor matrix elements, many people in thermal images are easily recognizable.
Some photos resemble the works of famous avant-garde artists. What is not Vasily Kandinsky?
Or this “Lady with a Dog”?
“Seek Thermal” allows you to study the device of various devices, “looking” inside an opaque case.
In the infrared range, a seemingly homogeneous plastic case of a hot water storage heater is observed with giblets. It turns out there are two tanks!
It is believed that the most dusty place in the house is the back of the refrigerator, because hot air circulating as a result of the cooling radiator contributes to the deposition of dust on it. If you consider that the refrigerator moves away from the wall only during repairs in the room, then the efficiency of the compressor decreases slightly, with a simultaneous increase in the electricity bill.
In this regard, in modern models, the cooling radiator is installed inside the side walls of the refrigerator, which on the outside represent a flat surface. But the thermal imager allows you to see its device.
In addition to studying the design of the refrigerator, the thermal imager helps save energy.
As a result of leaks in the door, the refrigerator cools not only the products inside, but the room, while consuming an increased amount of electricity and bringing the repair time closer. The gap in the seal is clearly visible on the screen, where the place of money leaking is shown in dark color (the usual photo of this refrigerator for us is in the album).
I always thought that the sole of the iron was warmed up evenly ...
The process of ironing clothes in the thermal range looks quite interesting.
Anyway, it’s better not to watch how the gas burner works, otherwise it will be scary to approach it.
The film "Burning gas (hot air) on the gas panel . "
Night shooting and the problem of excess weight.
The photographer always thinks about the necessary amount of light to get a high-quality image when taking photos / videos. The thermal imager breaks this stereotype - you can shoot with it at any time of the day, or even at night, which is very unusual.
There is no need for a flash or other illumination. All warm bodies perfectly contrast with a less heated background and are visible in absolute darkness. The thermal imager emits nothing, unlike For example, from a camera with IR illumination.
Observing people in the thermal imager, two main directions of energy consumption are immediately visible - maintaining body temperature (a person always radiates thermal energy) and movement. Therefore, overweight people have to consume more food in order to spend more energy.
Lost.
The thermal imager can be used to search for lost people, which will make it possible to detect them faster, since the method works even at night, when the classical methods are practically powerless.
Sometimes people are “lost" consciously. When searching for “losers” in paintball or while guarding objects, the thermal imager will give some advantage.
The thermal imager was not tested during the hunt, but city cats and dogs can be seen quite well. A flock of mongrels was observed from a distance of 120 meters, then they fled behind the house.
City hunting trophies in conditions of “exposure” to surrounding heat sources: A
running cat , playing the role of a hare.
Small dog depicting a fox.
Transport.
On the screen of the thermal imager, the diesel locomotive shines beautifully, because in its name there is the word “heat”.
Unlike the Lumiere brothers film, thermal shot of the train allows you to determine overheated axle boxes on the go. By the way, sound is not recorded during video recording, therefore, when watching a movie, you have to say it yourself: “Tukh-tukh-tukh-tukh ...”.
After the train, the picture that the infrared guidance head sees when flying to the plane is easily imagined.
Beautifully “burning” cars. Wheels, engine compartment, interior and silencer are the source of bright parts of the frame. On the roadbed there is a reflection of the muffler, which beautifully illuminates the bottom of the car.
In addition to asphalt, the reflection of heated objects was also seen on glass, ceramic tile, galvanized fence.
Rims, a silencer and an engine compartment are mobile “IR heaters” of the roadway.
After arriving at the parking lot, the car still pleases the thermal imager with its bright light for a very long time, therefore this fact can be used to detect cars that have been parked / stopped for a long time.
Now it’s clear why cats like to lie on the hood or under the car so much?
As with finding hot boxes of cars, the thermal imager can easily find a car with overheated wheels in the stream, which will increase road safety.
I liked the “Kamaz”, in which exhaust gases enter the body.
A stream of cars frozen in front of a red traffic light.
By the way, do you remember that one hundred thousandth of a second is the time between the ignition of the green traffic signal and the back tone?

Back to the survey of the home.
The house can be explored both outside and inside.
In the first case, they seek heat output (light elements on the thermal imager screen), in the second - the intake of cold (dark areas). The uniformity of radiation over the surface is also important.
One of the mistakes during construction is insufficient insulation of floor slabs or laying them so that they come close to the outer walls of the building. Since the plates are ducted, the cold air cooled at their edges circulates over the entire area, causing a cold floor problem. In the photo - heating the street with a brick house using floor slabs.
The situation is even worse when the foundation was built a little smaller. Since the floor slab has a standard size, it simply does not fit along the length, and as a result “sticks out” to the street. In addition to the installation error, in this case there will be significant heat losses.
In individual construction, channel technology for building walls is popular, when a brick wall is two planes connected across a distance by transverse bricks. The resulting voids (channels) are filled with insulating material: slag, sawdust, expanded clay, polystyrene, etc. This saves bricks, as the thickness of the walls can be reduced. The weak point of the technology in terms of heat loss is the transverse bricks through which heat loss occurs. You can calculate the area of hot spots.
The theory of open windows.
The heating temperature in apartment buildings and other houses is regulated depending on the outdoor temperature. But buildings have different thermal insulation efficiencies. In this regard, at a seemingly “legalized” temperature, in some houses it is comfortable, in others it is cold, and in the third the window panes do not close.
How to set the optimum temperature in the heating system of a particular house?
In addition to various thermal insulation of buildings, the outdoor temperature sensor, from the readings of which the temperature in the heating batteries of the ward’s house “dances”, often “shows” not what it should due to improper installation. Sometimes the system is supplemented with a control sensor in one of the apartments in order to more accurately adjust the result, but in this case there is a dependence of the heating temperature of the house on the readings of this sensor.
When examining houses with a thermal imager, it was noticed that he well defines open windows.
При помощи подсчета количества открытых окон можно повысить качество работы системы отопления дома и комфорт его жителей. Открытые окна интересуют не только домушников. Старые мастера, работающие в котельных, давно пользуются этим приемом: им достаточно одного беглого взгляда на дом, чтобы понять – холодно жителям или у них “перетоп”. Введение тепловизионной съемки дома позволит автоматизировать данный процесс.
Наблюдение за домом можно использовать для наладки гидравлического режима работы системы отопления.
Example. Often the comfort of some residents worsens due to an increase in the comfort of others (as Lomonosov said: if he arrives somewhere, then he disappears in another place). In this case, we are talking about turning the balcony into a residential area. Well, if the matter is limited only to its insulation. But sometimes the wall / window that breaks the balcony and the room breaks, and then the heating radiator is transferred to another place, with an increase in the number of sections. At the same time, the consumption of thermal energy increases and the hydraulic mode of the system changes, which negatively affects the neighbors in the risers.
The upgraded balcony is perfectly visible on the thermal imager screen. Its wall is blue / cold (insulated), and the windows burn brighter than all the neighbors.
A similar situation with garages. Heated specimens contrast with cold neighbors.
A special case of the theory of “open windows” is a cracked drive glass and a frame with slots.
When observing the house, you can clearly see the advantage of the glazing of loggias and balconies compared to cold porches with only one frame.
The thermal imager cannot peer through the window; it only displays the temperature of the glass surface. According to some reports , thermal imagers see through an opaque plastic bag. If a dress made of this material is sewn for the king, then a decent person in a thermal imager will look naked.
When examining one room, a warm rectangular spot was found on a wall about 10 cm thick made of gypsum block. The search for a heat source led to the kitchen (the other side of the wall) where the LCD TV worked. His heating was very weak to warm the wall, but nevertheless, the stain was clear. It is possible that gypsum in its characteristics is similar to the plastic bag mentioned above.
When examining heating radiators, the thermal imager allows you to see a violation of circulation when they are connected incorrectly, “clogged” or as a result of other reasons.
And here is the upper grille of the steel panel radiator.
Теплый пол повышает комфорт жителей, но его сверление для установки некоторых элементов вызывает головную боль у владельца. Повреждение трубки водяного контура или греющего электрического кабеля приводит к дорогостоящему ремонту.
Тепловизор сводит эту проблему на “нет”, так как все греющие элементы видны на экране, а метод “тепловой метки” позволяет прямо пальцем указать место, где на сверление накладывается табу.
A huge field of activity for the thermal imager opens when examining the premises from the inside. Places of heat loss are painted on the screen in dark colors. As a rule, these are door and window openings, corners of buildings, places of moisture on structural elements (which significantly increases thermal conductivity), insufficiently insulated parts of the roof, the above-mentioned elements of well masonry with transverse bricks and voids resulting from “subsidence” of thermal insulation.
With high humidity, problem areas often become a favorite mold place, but that's another story.
The device allows you to evaluate the quality of insulation, identify flaws in the construction and eliminate them, saving energy resources and money.
Such a hot handsome man spins a more heated pump for pumping water in the heating system.
An extensive scope of the thermal imager is electrical and electronics.
In the general picture, “interesting” places are marked, which are then examined in more detail upon close examination.
For example, an overheating contact and cable were detected in the driveway in a few seconds.
For electricians, the device can become pocket-sized, as Seek Thermal makes it possible to find an oxidized or loose contact in a live power assembly “on the go” and almost instantly.
When examining electronic components, the heating parts are clearly visible, but in the future you should try to cover the printed circuit board with film to reduce the effect of different emissivity of the materials used.
It will be interesting to see the battery charging by cells and banks, the effectiveness of various heat-conducting pastes when installing chipset radiators or high-power LEDs.
Did you serve in the army?
I don’t know how it is now, but nowadays, during the passage of the military commission, draftees checked flat feet, for which they moistened their feet with water or smeared with paint, then the guy stepped on a sheet, and the doctor assessed his suitability for military service using a picture on a piece of paper.
Using a thermal imager can save about a million sheets of paper annually. Save the forest - use the thermal imager!
The film " Check flat feet ".
Before shooting soap bubbles, it was assumed that the liquid of the soap solution, which has room temperature, in the process of inflation will turn into a film that quickly warms up with air, becomes bright in the picture and the ball flies up.
But something went wrong ...

Traditional Review.
Disadvantages.
1. A phone is required for use, and not all phones and operating systems are supported.
2. The “reverse” orientation of the connector on some Android devices necessitates the use of a cable. A miniature “flip” adapter is required.
3. To view a normal image, the phone’s camera is used, which causes problems in combining images due to the different arrangement of lenses.
4. In the temperature value display mode, it is not possible to point the point for measurement with a finger. shows the temperature in the center of the frame, there is a dissonance between the composition of the frame and the measurement at the desired point.
5. The area where the temperature value is displayed occupies part of the frame, therefore this mode was used little when shooting - the main information is carried by the temperature change in the frame, visible by color or brightness.
Pros.
1. Miniature size and low weight.
2. Sealed box for carrying and storage, allowing you to always carry the device with you.
3. MicroUSB cable included for Android devices with “reverse” connector orientation.
4. High performance at an affordable price for many people.
Although the price still does not allow you to purchase a thermal imager as a match, a dozen surveys of neighbors' houses will make it easy and quick to recoup this device.
The availability of the thermal imager significantly increases the number of monitored objects, which means it improves the mode of their operation, reduces the loss of thermal energy.
In all previous reviews, I disassembled devices to study their design. The thermal imager will be an exception, because after two films of the electronics fan mikeselectricstuff (which is worthy of our BarsMonster ), this makes no sense.
“ Seek Thermal camera teardown part 1 ”.
“ Seek Thermal camera teardown part 2 ”.
After viewing the second part, it becomes clear that although there has been less than one thermal imager in the world, the author evokes great respect and sympathy.
About two hundred photos resulting from working with “Seek Thermal” are located in the album “ Thermal Imager“ Seek Thermal ”. For some thermal images, their analogues are shown in the usual visible range.
Thanks to the device testing program , as a result of writing reviews, I managed to become the owner of two carbon dioxide meters (parts 1 , 2 and 3 ), an infrared thermometer (parts 1 , 2 ), a Geiger key fob and a thermal imager, in connection with which I would like to wish Dadget to expand the circle sales up to cars while maintaining the conditions of this program.
The company provides a 10% discount on purchases using the DD9F2D code.
Perhaps someone will offer a professional thermal imager for testing to compare its capabilities with “Seek Thermal”. But now it’s clear that the bar for accessibility of high-quality thermal imagers has fallen dramatically and many people are able to overcome it in order to jump into the beautiful and useful world of thermal images that can improve our world or just watch it from a different point of view.
When writing an article, he “threw” a list of objects of interest for shooting. But as they say - you cannot embrace the immense!
