Designing of Automatic Corridor Lighting System Using PIR Motion Sensor

Electrical energy increases its vast area day by day. Just like water it becomes necessary to save power for betterment of our future. So, an idea came into our minds why not we develop a technique for reducing the power demand by making corridor's lights efficient. In this documentation we discuss the experiment which was implemented in Electrical Engineering department's corridor of Rajkiya Engineering College Ambedkar Nagar, Uttar Pradesh, India. The main purpose of this experiment is to reduce the power consumption and make corridor lighting system to be more efficient. These experiments are mostly based on our observations that mainly college's corridor is used when the class period is going on and human movements during these period and the remaining time corridors are empty but the lights in corridor is always turn ON till the college is not over. To dealing this problem we use PIR (Passive Infrared) motion Sensor. PIR sensor is low-cost device and helps to minimizes the electricity bill. Finally, after implementation of this experiment we found drastic change in power consumption and it reduced by 77.78%.
