AUTOMATIC STREET LIGHT CONTROL WITH SOLAR PANEL

Abstract

Nowadays traditionally high intensity high intensity discharge lamps (HID) used for urban street Lights on the highways remain on whole night. A lot energy is wasted when there is no vehicle movement. This project is enhanced to detect the vehicle movement on the highways in order to switch on a block of street lights ahead of the vehicle moving towards them as well as switch off the lights when the vehicle passes away using IR sensor technology to save energy. In this project, we use a microcontroller named Arduino pro min. using 12v solar panel we will charge 8v battery. We convert this voltage to 5v by using a voltage regulator because the system of this microcontroller will operating in 5v.The IR Sensors are placed on the either side of the road to sense the vehicle movement and to send the logic commands to the microcontroller to switch on/off a set of LEDs. The project operates in three modes: complete ON mode, medium mode and dim mode. At 6 pm to 12 pm when more vehicles in the road the street light remain ON mode. At 12am-2am the vehicles are reduce on the road then the lights are on medium mode. And at 2am-6am few vehicles were remaining in the road then the lights are in dim mode. Thus, this system dramatically changes the intensity of the lights to save a lot of energy.
