Nowadays, human has become too busy and is unable to find time even to switch off the lights wherever not necessary. To save the electrical energy there is some idea.This can be seen more often in the case of street lights. The present system is in such a way that the lights will be switched on in the evening before the sun sets and they are switched off the next day morning after there is sufficient light on the roads. But the actual timings for these lights to be switched ON are when there is absolute darkness. With this, the power will be wasted up to some extent. This project gives the best solution for electrical power wastage. Also the manual operation of the lighting system is completely eliminated. The main aim of this project is to save energy. This project presents the design and the implementation of a lighting system which is able to detect the approach of the visitors and then turn the lighting onto the normal intensity to let the large scale sectors be bright enough. All lights are equipped with the energy-saving function which will turn itself to the dimming level automatically after the visitors’ leaving. PIR (Passive Infrared) sensors are utilized in the system instead of a video camera for the purpose of both cost-down and privacy issue. The project is developed with similar equipment but the concept is different. The project is developed in such a way saving is easy than to generate energy. The Project is Embedded Street light control system using 8052 Microcontroller. This project is very useful for commercial sign boards, advertising boards, street lights for automation lighting system. This system switches on the lights only in darkness. As it works with PIR sensor, no programming of timings and battery back-up is required. When the light focuses on PIR it sends signal to microcontroller, depending on that signal the lights will be turned off through relays and when PIR detects darkness the street lights will be automatically turned on. There is no need for manual controlling system. This is a simple and very useful system.
