Automatic Street Lighting Control System Using Microcontroller and Sensors

Abstract

Now-a-days the amount of power consumed by lighting and streets shares a major energy demand. Nowadays, human has become too busy, and is unable to find time even to switch off the lights wherever not necessary. Generally, street lights are switched on for whole night and during the day, they are switched off. But during the night time, street lights are not necessary if there is no traffic. Saving of this energy is very important factor these days as energy resources are getting reduced day by day. To overcome from this issue, a proper energy saving methods and lighting control to be implemented. The proposed work is to have two controls like, one is to switch of lights during no vehicle moments in streets and automatically switch it on when vehicles arrive and the other modes are to give less intensity light for pedestrian and to switch on bright mode during vehicle moments at sides on the roads. In this work the sensor is used for street arrangement, the Photo diodes and IR sensors are used to sense vehicle moments. The control signals of sensors have been fed to microcontroller 8051. Moreover the automatic and intelligent control schemes are required to control the complex lighting system due to growth of cities and standard of living.
