Smart Street Lighting System Based on Detecting Vehicle Movement

Energy conservation is an important matter as resources are decreasing at an alarming rate and this would create a lot of problems for the next generations. To overcome from this issue, a proper energy saving method and automatic lighting control needs to be implemented. This work proposes a model for modifying Street lights illumination using sensors at minimum electrical consumption as well as elimination of manual operation. In this work the LED lights are used as streetlights, LDR sensor is used for detecting light intensity for differentiating between daytime and night-time and IR sensors are used to sense vehicle movements. If presence is not detected, all nearby streetlights remain in the dim mode, which is 30% intensity for pedestrians, and only illuminate at 100% intensity when presence is detected. LED bulbs shall be used as they are better than conventional incandescent bulbs in every way. The intensity of LED can be controlled using PWM techniques. Through this proposed System the overall energy being utilized now-a-days for lighting is minimized. The automatic control of lighting is required to control the complex lighting system due to growth of cities and the standard of living.
