SMART STREET LIGHT

Electrical and Electronics Engineering

Urban areas in the entire world are dealing with increasing energy consumption and carbon emissions, a known contributor to climate change. Due to inadequate dimming control and low efficiency, current street lighting is wasteful in terms of energy spending, accounting for a major part of governmental electricity costs. Therefore, it has become desirable and of great importance to design a new smart lighting system that is more efficient and environmentally friendly. The main objective for this project is to design a smart lighting system which targets the energy saving and autonomous operation on economical affordable for the streets. This project is based on the embedded system and microcontroller 8051. An embedded system is combination of computer hardware and software, either fixed in capability or programmable, that is designed for specific functions with a larger system. The project is designed to detect vehicle movement to switch ON only a block of street light ahead of it(vehicle), and to switch OFF the trailing lights to save energy. Integrated sensors and controllers are used to design this project. Sensor identifies the movement of any object and offer command to the microcontroller to glow the road lights with 100% intensity and without any movement in the street give command to the microcontroller to glow with 10% of its maximum intensity. The proposed system is appropriate for street lighting in remote as well as urban areas where traffic is low at times. Along with energy saving it also tackles with the problem of power theft.
