PIR Sensor Motion Detector Module for Arduino, Raspberry Pi and DIY Projects

This PIR sensor detects human movement and gives a simple HIGH or LOW signal, so it is easy to use with Arduino, Raspberry Pi, and other boards. Connect three wires, upload a short sketch, and your project can react whenever someone walks past.

What You Can Build with a PIR Sensor

A PIR sensor is the usual choice for projects that need to know if someone is in the room. You can build a motion alarm, an automatic light, a door entry alert, or a visitor counter. It senses the infrared heat that people give off, so it works even in a dark room. Most modules also have adjustable sensitivity and delay time, so you can tune them to your project.
