PROTOTYPE AUTOMATIC STREET LIGHT

Abstract

The automatic street light control is an electric device designed to provide an alternative to the switching system of existing one. The automatic street light control become imperative to overcome the shortcoming of the previous and presently existing methods of switching to control light supply. Automatic street light made use photoelectric device as sensor, it sense light and darkness so that light will automatically switch ON and OF. It is made up of different unit to perform and serves its purpose. This paper aims at designing automatic street light system. Nowadays, human has become too busy, and is unable to find time even to switch the lights whenever not necessary. The present system is like the street 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. This is the best solution for electrical power wastage. In this system the two sensors are used which are light dependent resistor LDR sensor to indicate a day /night and the photoelectric sensors to detect the movement on the street. The Microcontroller PIC16F877A is used as brain to control the street light system. Where the programming language used for developing the software to the microcontroller is C- language. Finally, the system has been successfully designed and implemented as prototype system. It is suitable for use at home areas where illumination is important.
