PIR stands for Pyroelectric Infrared (many times, they are also referred as Passive Infrared sensors). This is because their principle of operation is based on the detection of infrared energy emitted by a moving body.
The PIR sensor can detect infrared signals from a moving person or moving animal, outputting switching signals.

One important thing to mention is that when motion is detected, the output will stay high for 2.3 to 3 seconds after the motion stops.
Regarding the power supply, it can work with voltages of both 3.3V and 5V. The device has a detection range of 7 meters and a detection angle of 100º.
This module should be used together with EASY plug control board.
