Abstract: The main aim of this study is to reduce electricity wastage and manpower that is required to switch highway lights ON and OFF. Highway lights are one of the most important part of the modern society as they facilitate better vision at nights while driving and provide safety on roads. Highway lights, however, consume a lot of electricity. This study proposes a system that would reduce electricity wastage with the help of embedded technology that would control the highway lights based on the sunlight and motion on the road. With the help of Light Dependent Register (LDR) sensor, day or night can be detected. When night is detected by the LDR the lights on the highway would autonomously turn ON and when day is detected it would turn OFF automatically. The lights would be at 30% intensity when it is turned ON and as soon as it detects motion on road with the help of ultrasonic sensor it would increase the intensity to 100% and when the ultrasonic sensor doesn’t detect anyone on the highway the light intensity would go back to 30%. In addition, to this current sensor data is collected and stored in the database as it can be used to detect if the highway light is working or not. The system is reliable and cost-efficient as all the equipment used are less costly and available easily.
