Passive Infra Red sensors and the Raspberry Pi

It’s taken a while to arrive, but finally I have received my infra red sensor that I ordered from china via EBay.

It’s a simple circuit: just power and 1 GPIO port. I followed the circuit I covered in a previous post, and produced the following.


The sensor has two things you can adjust: sensitivity and time – the amount of time the circuit stays on – between 2 and 200 seconds.
