This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low.

You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin.

If any of the motion sensors go off, the input pin will be pulled low. The connector is slightly odd but has a 0.1" pitch female connector making it compatible with jumper wires and 0.1" male headers.

  • Red wire is power (5 to 12V).
  • Brown wire is GND.
  • Black wire is open collector Alarm.
  • This unit works great from 5 to 12V (datasheet shows 12V).
