PIR sensors, often referred to as, "Passive Infrared" or "IR motion"  sensors, enable you 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, that room will  increase in temperature slightly) and hence sense motion. 

This  one's great, as it can be powered  via the 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 PIR includes an adjustable delay  before firing (approx 0.5 - 200 seconds), has adjustable sensitivity and  two M2 mounting holes! It runs on 4.5V-20V power (or 3V by bypassing  the regulator with a bit of soldering) and has a digital signal output   (3.3V) high, 0V low. Its sensing range is up to 7 meters in a 100  degree cone.

Setup with Raspberry Pi

This infrared obstacle/object detection sensor is super easy to use. It comes with a potentiometer to adjust the sensitivity. The output is a digital signal so it is easy to interface with any microcontroller such as Maker UNO, Mega, Leornado, Zero, 101, or even the Raspberry Pi or Raspberry Pi Zero. This infrared sensor offers simple, user-friendly, and fast obstacle detection via infrared reflection, it is non-contact detection. As it is based on light reflection, the detection varies with different surfaces. And any infrared source might also interfere with the detection.

It comes in a pair of Infrared emitter and receiver at the front of the module, whenever an object blocks the infrared source, it reflects the infrared and the receiver gets it and the signal goes through a comparator circuit on board. Depending on the threshold that is being adjusted, it will output logic LOW at the output pin and the green LED will light up to indicate the detection. Turning the onboard potentiometer clockwise will increase the sensitivity and further increase the detection range. Compatible with 5V or 3.3V power input.

Note: Please make sure that there is a gap between the emitter and the receiver so that the sensor can work properly.
