Features:

PIR sensors are often referred to as "Passive Infrared" or "IR motion"  sensors which have the ability to sense motion. Everything emits a small amount of infrared radiation (IR), and the hotter something is, the more radiation it emits. PIR sensors are able to detect a change in average IR levels of their detection zone e.g. when a human enters a room.

This unit runs on 5V-20V power input or 3V by bypassing the regulator with a tiny bit of soldering and has a digital signal output of 3.3V high, 0V low.It can also be powered via  Raspberry Pi's 5V output, and be read directly from the Raspberry Pi's GPIO input as the sensor has a digital 3.3V output.

* This module will need to to be assembled with a few other components in order to work correctly. Some electrical knowledge is required. Please research before buying
