This paper gives the best solution for electrical power wastage. 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. Nowadays, human has become too busy, and is unable to find time even to switch the lights wherever not necessary. This paper aims at designing and executing the advanced development in embedded systems for energy saving of street lights. Finally, the system has been successfully designed and implemented as prototype system. 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. In this paper the two sensors are used which are Light Dependent Resistor LDR sensor to indicate a day/night time and the photoelectric sensors to detect the movement on the street. Also the manual operation of the lighting system is completely eliminated. this paper gives the best solution for electrical power wastage.
