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.
