Arduino based Smart Street Light System

The main motive of street lights system is to illuminate the environment during night time in order to prevent the accidents and public safety on roads. These street light systems required huge amount of electricity and man power for the maintenance. India is one of the major developing countries across the world which is facing the power problems due to enormous increase in population. The minimization of power shortage is very challenging issue in this modern era because the natural resources like coals and fossil fuels are diminishing rapidly. Thus, to save the power and road accidents during night times; it is essential to introduce an efficient street light management system which can improve the efficacy. In this work, an Arduino based Smart Street light system has been proposed which uses light dependent resistor for ON/OFF the street lights automatically during night times or cloudy environments. Moreover, a passive infrared sensor has been used for vehicle motion detection during night times. The street light is in OFF position during day time irrespective of the vehicle traffic, whereas; the street light is ON whenever there is a vehicle movement detected by PIR sensor during night times. The proposed system is best suitable for highways, smart villages, and rural villages.
