ABSTRACT:
The trending demand of alternative sources of the energy is required to the growing demands of the people. It can be done in two ways; first one is to find alternative resource of energy and another one is by reducing the energy consumption of the present available resources. In this paper we discuss about the second one that is reduce the energy consumption. This is basically the study of streetlights with control lighting based on microcontroller. A smart street light system consists of a LED light, a brightness sensor, a motion sensor, a communication network. The lamps turn on before the vehicles come and turn off or reduce the brightness when no one is there. It will be difficult for walkers and drivers of vehicles to distinguish between smart street lamps and the conventional street lights, since street lamps all turn on before they come. Conventional street lighting systems in areas with a low frequency of vehicles are online most of the night without purpose. The result is that a large amount of energy is wasted senselessly. Public lighting in streets, tunnels, ports and squares etc. can account for about 30% of urban energy consumption. Based on environmental and economic factors, cities need smart lighting system which reduces energy consumption, maintenance cost and CO 2 emission.
