Abstract: This paper proposes energy efficient smart automatic street lighting system. The main objective is to design an energy efficient microcontroller based system which gets turned on and off automatically depending on the ambient lighting. This system consists of LDR, light sensor, and a set of the Light Emitting Diode (LED) module. The system was programmed to automatically turn off during the hours of daylight and only operate during the night and heavy raining or bad weather. Several numbers of tests have been conducted to test and validate the proposed prototype in the different environment. As conclusion, around 77%-81% reduction in power consumption can be achieved through this proposed automatic street lighting system for energy efficiency system design. Also, a demonstration with a real-time proto type model involving costs and implementation procedure has been developed using Internet of Things (IoT) to visualize the real time updates of street processing and notifying the changes occur.
