This paper proposes energy efficient of automatic street lighting system based on low cost LDR circuit. 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 is consists of a simple light detecting resistor, sunlight detecting sensors and LEDs. While, the controlling and managing of the system is based on the number of traffic and five different level of street light brightness has been used for lighting up the street and proportional to the number of traffic. 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 environments. LDR based project main idea is to develop a application which can control the electricity usage in street lights or saving the energy when nt in use. LDR is used in this application for sensing light intensity. LDR controls power by controlling output resistance which is dependent on light intensity. This application can also be used in industries, house hold applications and many other fields where power consumption is more. The solar panels will feed the system with solar power, which will be charging the battery during the day. At night the battery will be discharge through the project processes. The battery and the streetlights will be monitored to observe their level and performance in the operating board. Research have been done about transmission medium which will be wireless by using transmitters and receivers. This medium will allows the information to transfer from part to another in the system.
