Working Principle

The PIR sensors are commonly used in many appliances these days. The sensors have ability to sense motion and can be used to detect any trespassing occurrence in the sensor's range. The PIR are made out of pyroelectric sensor, a material having ability to generate electricity after given heat or cold, thus giving them ability to detect levels of infrared radiation. As every living body emits some amount of heat from their body, hence the sensor detects the change in amount of IR emission when someone passes by. The sensors are split into two, so they can sense out past some distance. When a worm body enters the sensor's perimeter, firstly one of half detects it and the other remains the same, causing a positive differential change in both half of the sensors and when the body leaves the perimeter the exactly reverse happens causing negative differential change. The sensors detects the change between these two and gives the desired output.
