An automated road light control system using relays and light sensors

Abstract

An automated road light control system is a simple and also a very useful concept for the human life, system comprises of a transistor used herein as a switch to control the ON/OFF the light automatically as per commanded by the microcontroller informed by the sensors. The lights turned ON automatically during night when there is presence of an object, and turned OFF at day time or the absence of the object. This is performed by the system with the help of photoelectric sensor and LDR.
