PIR Motion Sensor is used for all purpose security system. All live objects whose body temperature is more than 0 degree Celsius emits the heat in form of infrared radiation through their body. This radiated signals are invisible to human eye. These signals can be detected by using PIR sensor which is specially designed for such purpose. In passive infrared (PIR) sensor, passive word indicates PIR sensor does not generate or radiate any energy for detection purposes. They detect the infrared radiation emitted or reflected from human or animal.
