This is a simple to use motion sensor. If anything moves, the ‘alarm’ pin will go low. This unit works from 5 to 12V. You can also solder a wire past the 5V regulator on board to make this unit work at 3.3V. The alarm pin is an open collector. The PIR can sense abrupt changes in scenery as far as 3m away.
