How to Use a Thermal Camera with a Raspberry Pi
There are several IR camera sensors now available to electronics hobbyists that allow you to measure thermal radiation. All it takes is the addition of a microprocessor to turn an off the shelf sensor into a full-fledged thermal camera.
Keep in mind the resolution offered by these sensors is much lower than what you would find on a commercially available thermal camera. They are still sufficient enough to act as a person or animal detector, an automatic door sensor, or a contactless thermometer.
The Raspberry Pi offers adequate processing power and with its GPIO pins an easy way to connect sensors. Scripting languages such as python also run on the Pi and can be made to interface with the sensor. This combination gives a flexible testbed for creativity.
What else you'll need
This guide was written using a Raspberry Pi 3, though any Pi newer than the first generation Raspberry Pi should use the same GPIO pinout and the sensor would connect the same. The operating system used for this guide is the latest version of Raspberry Pi OS with Python 3 and Git installed.
