SMART STREET LIGHT CONTROLLED SYSTEM

Electronics and Telecommunication Enginering

This project illustrates the street light glowing system on vehicle detecting movement. Controlling of street light is of almost importance in developing country like India to reduce the power consumption. This paper presents a street light control system which combines various technologies: a timer, a statistics of traffic flow magnitude, photodiodes, Light Emitting Diodes (LED), power transistors. IR Sensors used on either sides of the road send logic command's for the LEDs at the output to get glowing for a patch ahead Intensity control is also possible by pulse width modulation based on sensing the movement and density of vehicles. The project is designed to detect vehicle movement on street to switch ON only a block of street lights ahead of it (vehicle), and to switch OFF the trailing lights to save energy. During night all the lights on the street remains ON for the vehicles, but lots of energy is wasted when there is no vehicle movement. For auto power consumption when there is no vehicle on the Street Light this includes controlling a circuit of street lights with NE555P, specific IR Sensors & Light Dependent Resistor (LDR) is a type of sensor which actually does this work and senses the light as our eyes does. As soon as the sunlight comes, visible to our eyes it automatically switches OFF lights. Total process operation in Solar Power.
