The DIY-Thermocam is an open-source, do-it-yourself thermographic camera for everyone.

The aim of this project is to give private persons, educational institutes or small companies access to a portable and low-cost thermal imaging plattform.

There are various applications like finding heat leaks in the insulation of buildings including windows, the analysis of electric or mechanical components, the detection of persons or animals and many more.

Offered as an easy to assemble kit with almost one-hundred components, the DIY-Thermocam allows you to take advantage of the versatile possibilities of thermal imaging!

The large firmware written in Arduino compatible C++ code can be used as it is adapted to your own needs.

For more information, check out the project's website:


  • Fast ARM Cortex M4 processor running at 144 MHz
  • 80 x 60 pixel long-wave infrared array sensor for live thermographic images
  • Additional 640 x 480 pixel optical camera for visual images
  • Single point-infrared sensor for high-precision spot temperatures
  • 3 operating modes: thermal only, thermal + visual, video recording
  • 5 color schemes: rainbow, ironblack, grayscale, hot, cold
  • 3.2 inch touch LCD display with bright colors and wide angle
  • Save thermal and optical images with a resolution of 640x480 pixels
  • Save videos and interval pictures
  • 2GB of internal storage, accessible over USB as mass storage on any computer
  • 2500 mAh lithium polymer battery for long operation time
  • Open-source firmware written in C++, modify / extend it to your own needs or use it as it is
  • Standalone firmware updater that runs on any windows computer, update over Mac & Linux is also possible

The diy thermocam website (Github) shows what looks like an earlier version (2.3) of the PCB. It does not feature a laser. Of course I want to build something with LASERS! When will version four be published?

  Are you sure? yes | no
