Mini PIR Motion Sensor Module

PIR sensors are used to sense movement of people, animals, or other objects.
They are commonly used in burglar alarms and automatically-activated lighting systems.
They are commonly called simply "PIR", or sometimes "PID", for "passive infrared detector".
These sensors can be used with Arduino® boards or other microcontroller boards.

Operating voltage is 3-15V and the detection range is 4m.

This product works the same way as this one. Only difference is the size.
