DIY-Thermocam - An open-source, do-it-yourself thermal imager

DIY-Thermocam - An open-source, do-it-yourself thermal imager

 

image

 

The DIY-Thermocam is a do-it-yourself, low-cost thermographic camera based upon the famous Teensy 3.2 mikrocontroller. It uses a long-wave infrared sensor from FLIR to provide high quality thermal images.

 

The aim of this project is to offer a cheap, open-source thermal plattform for private persons, educational institutes or small companies. There are various applications like finding heat leaks in the insulation of buildings including windows,  the analysis of electric components, as well as exploring at night.

 

The large firmware written in Arduino compatible C++ code can be used as it is or modified / extended to your own needs. That allows the DIY-Thermocam to be used as a versatile basis for various, different thermal applications.

    How is that you use a Flir sensor but have better resolution and much better accuracy than Flir can manage ?

     

    Do you have any test reports that can back up these claims ?

    Thanks for your answer ! I know the price is not comparable to the cheap smartphone addons on the market, but if you compare it to a stand-alone thermal imager even from big companies like Seek or FLIR (and I am just a single student at the age of 23), it's still in the price range.

     

    The project you mention also looks very interesting image Version 1 - 3 of the predecessor of the DIY-Thermocam, the Cheap-Thermocam, also used a single IR sensor to scan the image. That was cheap of course, but took some time to create an image. The Lepton sensor in the DIY-Thermocam is a real 80 x 60 LWIR sensor, and there will be an upgraded version with 160 x 120 pixels in the near future, that can also be plugged into the device.

  • This looks great, but 429 euro is still pricey though.

    For lower resolution, there is an open source BeagleBone Black Thermal Imaging Camera here. It uses a Melexis sensor but nowadays

    would be better (and cheaper) to replace with Panasonic Grid-Eye (£28+VAT).

    The project uses a $7 colour LCD screen, and bilinear interpolation to produce a reasonable image out of

    the low-resolution sensor, and works quite well with video here the individual fingers of a hand are visible.
