This paper aims at designing and executing the advanced development in embedded systems for energy saving of street lights. Nowadays, human has become too busy and is unable to find time even to switch the lights wherever 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 paper gives the best solution for electrical power wastage. Also, the manual operation of the lighting system is completely eliminated. In this paper, the two sensors are used which are Light Dependent Resistor LDR Sensor to indicate a day/night time and the ultrasonic sensors to detect the movement of the object. when the movement of the object is not detected in the ultrasonic sensor it becomes glow in low intensity And if anyone crosses the sensor path at that time it will glow at high intensity. After the object passes away from the sensor path it automatically converts high intensity to low intensity.
