Mini Thermal Camera

Build a mini thermal imaging camera with Adafruit PyBadge and MLX90640 IR Thermal Camera breakout. Record and analyze images for revealing the heat in circuits, machines and even humans!

PyBadge & MLX90640

The IR thermal camera sensor uses the STEMMA QT connection so it easily plugs into the Adafruit PyBadge.

An external slide switch is used to power the circuit on and off. A metal ball button is used for reset.

A 3.7V 320mAh battery connects directly making this a portable project with rechargeable USB.
