Automatic Street Light Control System

Abstract

The system elaborates the design  and construction of automatic light control system. The developed electronic system eliminates the disadvantages of the existing systems. Based on the results the microcontroller calculates and automatically detects geographical area and retrieve relevant data for sunrise and sunset in the area, respectively ensures very precise ON/OFF mode of the lighting system. The circuit uses a light sensor to sense the light. It doesn’t need operator maintenance and initial installation setup. The developed electronic device increases bulb life in result of the dimming effect. On the other hand this decrease of the illumination leads to reduce in the energy consumption. By using this system manual workare removed.It automatically switches ON lights when the sunlight goes below the visible region of your eyes. It automatically switches OFF light under illumination by sunlight.This is done by a sensor called Light Dependant Resister(LDR) which sences light actually like our  eyes.
