3PCS Keyestudio PIR Motion Sensor for Arduino UNO R3 IR Motion Sensor for Human Body Motion with Keyestudio Packing Box

The Pyroelectric infrared motion sensor can detect infrared signals from a moving person or moving animal, and output switching signals. It can be applied to a variety of occasions to detect the movement of human body.

Conventional pyroelectric infrared sensors are much more bigger, with complex circuit and lower reliability.
Now we launch this new pyroelectric infrared motion sensor, specially designed for Arduino. This sensor integrates an integrated digital pyroelectric infrared sensor, and the connection pins.

It features higher reliability, lower power consumption and simpler peripheral circuit.
