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.
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. The 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 to a single input pin. If any of the motion sensors go off, the input pin will be pulled low.
The circuit board measures 35.4 x 30.6mm.
Please Note:
- You will find a common 3-pin JST! This makes the PIR Sensor much more accessible for whatever your project may need. Red = Power, White = Ground, and Black = Alarm.
