Vehicle Movement Based Street Light Using PIC

Vehicle Movement Based Street Light Using PIC

Vehicle Movement Based Street Lights Project mainly aims at saving energy. The system acheives this by switching on the street lights only when a vehicle will pass by it and to switch off the lights when there are no vehicles in the street. Thus the system can be used to save a lot of energy by allowing only the required lights to be turned ON as soon as the system senses vehicle movement and to switch off the lights as soon as the vehicle moves ahead. Thus unlike the current system which keeps the street lights ON, irrespective of the vehicle movement. The system uses another mode of operation where the street lights are turned ON with 10% intensity and when the vehicle movement is sensed, the system switches ON lights with 100% intensity.PWM is used for intensity control through microcontroller. The sensors senses the vehicle movement and the sends messages to PIC controller which then the send commands to either switch ON or swithch OFF the streeyt lights.
