Automation of Room Lighting System Using Arduino and PIR Sensor

In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the usage of Arduino and PIR Sensor is a on hand project, place room light will mechanically flip ON upon sensing an object action besides proceed to be grew to supply up on till the man or girl has left or there is no gesticulation. Operation of this assignment is same on hand and is described here. Initially, when there is no object motion, the PIR Sensor does not appear to be at any man or girl and its data OUT pin sojourns LOW. As the man or woman pass in the room, the trade in infrared radiation in the room is detected with the beneficial useful resource of the PIR Sensor. Consequently, the yield of the PIR Sensor will flip out to be HIGH. Since the OUT pin of the PIR Sensor is allied near Digital 8^th Pin of Arduino.
