This paper proposes energy efficient automatic street lighting system based on low cost microcontroller. The main objective is to design energy efficient based controller for controlling the Light Emitting Diode (LED) based street lamp via appropriate lighting levels control. This system consists of a microcontroller, light sensor, PIR sensor and a set of the LED module. The controlling and managing of the system is based on the density of traffic and five different level of street light brightness has been used for lighting up street proportional to the density of traffic. The system was programmed to automatically turn off during the night. Several numbers of tests have been conducted to test and validate the proposed prototype in the different environment. As conclusion, around 77%-85% reduction in power consumption can be achieved through this proposed automatic street lighting system for energy efficiency system design.
