IoT-GSM-based high-efficiency LED street light control system (IoT-SLCS)

Today, population density shifts towards urban centers have resulted in the constant rise of energy consumption in cities. Due to the cost and technical restrictions of strengthening the infrastructure at the same rate, alternative energy sources must be sought in order to meet these increased energy demands. This study presents a street lighting system which consumes minimum energy from the city network by using solar energy to charge the battery during the day. This intelligent charging system will increase battery life and store solar energy. During the night, the battery is used for illumination until it is depleted, and only then is the energy from the city network used. Moreover, with the development of TCP/IP communication with centralized software on the cloud via GSM, the high-efficiency LED lighting is managed and monitored according to the level of daylight and the volume of traffic detected. Thus, with this system, a lead-free environment, lower CO2 emissions and energy savings can be achieved.
