Energy Efficient Street Lighting System

Abstract

This paper presents an energy efficient street lighting system which provides some percentage of saving in energy. The main objective is to build an automation system of street lighting using a low cost microcontroller which Arduino to achieve energy is saving. Light Emitting Diode (LED) is represented as the lighting system. Whole system is controlled by two sensors which are Light Dependent Resistor (LDR) and Passive Infra-Red (PIR) sensor. This system operates in night times using LDR sensor. And automatically adjusts the illumination of LEDs according to motion (vehicle or human) using PIR sensor. The system is implemented for two way road with a junction. Street lights will be 100% illumination when only there is road user; otherwise it will be at 30% illumination. This design can save a large amount of energy consumption compared to conventional street lights that keep lights ON during night. Therefore this system has been successfully designed and implemented as a model.
