PIR Motion Sensor (JST)

It 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’ll be able to also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses [email protected].

The alarm pin is an open collector meaning you’ll need a pull up resistor on the alarm pin. The open drain setup allows more than one 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.

We’ve got after all up to date the connector! Gone is the old “abnormal” connector, now you’ll find a common 3-pin JST! This makes the PIR Sensor a lot more accessible for no matter what your project may need. Red = Power, White = Ground, and Black = Alarm.
