Description: 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.
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). 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.
