Vehicle Movement Based Street Light System Using PIC Microcontroller



Vehicle Movement Based Street Light System Using PIC MicrocontrollerVehicle movement based street light system using pic microcontroller is a system, which turned on or off the street lights after sensing the vehicle movement in a street. Basically, this an energy conservation system which saves the energy when there is no any vehicle movement in a street. Now days if we see in our vicinity areas, then there are so many lights which are always in turned on condition (day and night). Besides this, turned on/off the street light on daily bases also a big problem. So, for resolving this problem and energy conversation here we have designed a system that is called a vehicle movement based street light system using pic microcontroller with the help of pic 18F452 microcontroller, transformer, voltage regulator and IR sensors. So many streets lights could be turned on/off automatically by using this single system. In other words, this system turned on the lights when any vehicle pass through the street and turned off after passing them.
