Smart Street Light System Powered by Footsteps

Abstract

Currently, enormous amount of electrical power is being used by street lights, which remain switched ON throughout the night. This causes a huge wastage of electrical power across the whole world and it should be minimized. The main purpose of implementing automatic street lights is that lights will switch ON with full intensity only when there are vehicles or pedestrians on the road and remain off otherwise. The street lights can be powered by the electrical energy generated through the pressure applied by footsteps and vehicles. So we don't need to provide power to the street lights separately. The automatic street light system comprises of DC lights, lux meter, PIR sensors, piezoelectric sensors, LDR and ultrasonic sensor. Our main purpose is to make such a street light system in which intensity of street lights increases when a car comes closer to it and decreases when it moves away from the light pole.
