PIR Motion Sensor
Pyroelectric ("Passive") InfraRed Sensors
PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. This guide will show you how they work, how to use them, and give you some project examples.
