this is a street light control project,that glow on detecting vehicle
movement,This project is designed to detect a vehicle movement on road
to switch on only a block of street lights that are ahead of the
vehicle, and to switch off the glowing lights when the vehicle passes
away from the lights. This will help to save electrical energy.
Generally street light switched on in night and switched off in night this approach is good for busy road, but in a empty road lights are always switched on and it consume lots of energy.this project is a great solution for making energy efficient street light.
Lights are always switched on with low intensity using PWM signal, when a vehicle comes to road intensity of lights nearer the vehicle will increase.
