The PIR Sensor senses the motion of a human body by the change in surrounding ambient temperature when a human body passes across. Then it turns on the lighting load to which it is connected. The lighting load will remain ON until it senses motion. Once the motion is seized it switches OFF the lighting load.
Wireless sensor-based control has drawn attention of many industries because of the reduced cost, easy mobility, easy maintenance, power management etc. Wireless Sensor based systems have been deployed in industries, army and in household for various applications such as monitoring, maintenance, security etc.
