Design and implementation of solar based smart street lightning system

The huge amount of electrical power is consumed in lighting the streets. However, vehicles pass with very low rate in specific periods of time and parts of the streets are not occupied by vehicles over time. In this paper, we propose a system that detects the vehicle from certain radius and automatically switches on the light till the vehicle crosses a particular radius. Logically, this system may save a large amount of the electrical power and increases the lifetime of lamps. Also as the energy used for lightning is taken from solar energy at day time. Thus energy used is renewable. A GSM based system is also integrated in the design which is used to send a message to substation if any fault in street lights is detected. The major operation of this system is to save the excess use of electrical energy by using solar panels and motion sensors along with less manpower requirement since the GSM modem can detect the error and location and inform it to the station. This system automatically controls and monitors the light of the streets. It can light only the parts that have vehicles and help on the maintenance of the lighting equipments.
