Me PIR sensors are used to detect motion from animals/ humans from about 6m away. If anyone moves in that range, the sensor outputs HIGH on its SIG pin. With a potentiometer soldered on its circuit board, you can adjust its detecting range according to your needs. Application ideas: motion detection, anti-theft system, automation switch.
Note: When you power it, you may need to wait 10 seconds until the sensor is initialized.
