By sticking this sensor on a breadboard with an Arduino Mini and WiFly network adapter, [Rob] is able to pull the data down from the IR sensor to his iPhone and overlay it on the feed from the camera.

A temperature sensor monitors the room temperature from afar, and a solid-state relay (SSR) controls the power for the heater. Now he just needed a PID library — readily available from Arduino ...

Hell, you can get heat vision in an iPhone case now. Now, with this tiny board, you can bring heat vision into any of your Arduino/Raspberry Pi DIY projects.
