PIR Motion Sensor (JST)

Model No: SEN-00047

TK. 1221.33

Availability: In stock


Category: Motion

Supplier: SparkFun, USA

This is a 3-pin 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. 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.

Note: The colors of the wires can vary greatly. Looking at the unit from the top, the middle wire is ground, the left-most wire is the alarm, and the right-most is the power.

Q: I have a question about this model. Can it be used as presence detector or it is only usable for detecting motions. Actually I want to make a power saving lighting system for bed room. In a room there may be no motions every time while a person is present in that room. he can sleep or in sitting position but not moving. Questioned by mzajewel, 25-Aug-2016
