Infrared camera for smartphone FLIR ONE Bashny.Net

Imager — a device that allows you to see the temperature differences of objects. It is possible to detect overheating wiring and equipment, heat leak in the house, to roughly measure the temperature of objects, including those located far enough.

More recently thermal imaging cameras were very expensive and the price starts from 100 000 rubles. Recently began to appear relatively cheap cameras, but the resolution matrix are very low. For example, the cheapest cameras on Aliexpress are from $240 and have a matrix of 60 by 60 pixels.

An interesting alternative to thermal imagers for smart phones. They are relatively cheap, have a matrix of higher resolution.

Today we will talk about the FLIR ONE thermal imager, developed by FLIR, which is considered a recognized flagship of thermal imaging technology.





The main feature of the FLIR ONE is the presence of two cameras — thermal and conventional, the image from which the combined and the picture becomes more detailed.





This is the second generation FLIR ONE. Thermal matrix has a resolution of 160x120 pixels (from FLIR ONE the first generation was 80x60), and a matrix camera of 640x480 pixels.

The imager has a built-in battery allowing it to run for 45 minutes and doesn't drain battery power of the smartphone.

Sold in two versions — with Lightning connectors for iPhone and MicroUSB connector for Android smartphones. With a thermal imager can only work those Android smartphones that support USB OTG (you can check by sticking in a MicroUSB flash drive with this connector).
 



Included thermal imager, carrying case, neck strap, two adhesive bands (they can be pasted on the imager side of the connector to the body of the device tightly to the body of the smartphone), a very short instruction and address from the head of the company.





On the right side of the case — the connector MicroUSB, used for charging the thermal and charging indicator.





On the left side — the power button and the status indicator on the inside of it.



It looks like the side of a thin smartphone with an attached camera, which glue the rubber gasket.





Both cameras have a fixed focus that allows you to observe objects located at a distance from 15 cm to infinity. The angle 46 horizontally and 35 vertically.

Regular app, FLIR ONE displays the combined image.
 





The program continuously displays live thermal imaging video at update pictures at about 10 frames per second. Approximately every 30 seconds the picture freezes (the unit is calibrated, it can be disabled).

The app can take photos, video, time-lapse, thermal imaging and even panoramas.

The application can display the temperature, but it is shown only in the center of the image. Display of minimum and maximum no. You can view them in the same app when viewing saved pictures. While viewing the saved frames it is possible to view a picture with an ordinary camera, by swiping your finger up or down. Here you can see that thermal image is slightly shifted to the side due to the fact that the distance to the object was too small.





A separate application FLIR Tools, which exists not only for smartphones but also for Windows and MacOS, can handle files saved in the FLIR ONE app. You can see and save only a thermal image or photo, you can adjust the transparency and blending photo with a thermal image, it is possible to replace the color palette, overlay photo shapes, inside which will display the minimum and maximum values of the temperatures.

There is an alternative app Thermal Camera, which features the simultaneous display of both temperatures at the center and minimum and maximum temperatures. In the lower right corner shows the combined image at the top of the screen only thermal imaging.





Unfortunately, this app on Huawei smartphone P7 is unstable, sometimes freezes and crashes.

Using a thermal imager can see a lot of interesting things. For example, if you put a hand to the wall and get it on the wall for a few more minutes will remain heat signature.





The heat from the battery and cold from a bad seal balcony doors and Windows.
 





Led light bulb.





Water flows from the tap. Once seen, where hot and where cold water.





Thermal selfie.





City view from the balcony. It is seen how the leaked heat.





As you know, the coldest point of the cat's nose.





You can even see how warm people wear on how she misses the heat.





Clearly visible open Windows.




The imager should not be regarded as a precision thermometer. I compared the readings of the three imagers — professional and quite expensive Testo 875, the FLIR ONE and Seek Thermal:
 



As the table shows, the difference in the readings of the thermal imager comes to seven degrees, and it fluctuates in one direction and then the other.
