The DIY Thermocam Version 3 has been redesigned to offer 3x the performance of the predecessor, making thermal imaging much more accessible and fun!

The aim of this project is to give private persons, educational institutes, and companies access to a portable, affordable, and customizable thermal imaging platform that is based on open-source software and hardware.

There are various applications like finding heat leaks in the insulation of buildings, the analysis of electrical or mechanical components, the detection of persons / animals, or even mounting it on a drone and recording continuous or time-lapse images.

Constructed as a self-assembly solution, the device allows you to take advantage of the versatile possibilities of thermal imaging. Both the software and hardware are open-source, allowing you to modify or extend the functionalities of the device and the software ecosystem to your own needs!

The DIY-Thermocam V3 self-assembly KIT contains all required components excluding the FLIR Lepton 2.5/3.5/3.1R and the Lepton Breakout Board V2. If you don't already own a FLIR Lepton or Lepton Breakout Board V2, these can be purchased separately.
