Automatic Street Light Controller with Energy Consumption Measurement using Arduino

This project presents the design and implementation of an Automatic Street Light Controller with Energy Consumption Measurement using an Arduino microcontroller. The primary objective is to reduce energy wastage by automating the operation of street lights based on ambient light levels and to monitor the energy consumed by each light. The system uses a Light Dependent Resistor (LDR) to detect the intensity of surrounding light. When the ambient light falls below a predefined threshold (e.g., during night-time or cloudy conditions), the Arduino activates the street lights. Conversely, when sufficient daylight is detected, the lights are automatically turned off. This intelligent switching helps conserve electricity and extend the life of lighting fixtures. The sensor readings are processed by the Arduino and can be displayed on an LCD module or transmitted to a remote monitoring system for further analysis. This feature allows municipalities or maintenance teams to track energy usage and identify malfunctioning units.
