The Smart Electricity Saver, is an innovative hardware project that optimizes energy consumption. By integrating a light sensor and window control mechanism, this system adjusts lighting conditions based on the presence of sunlight. The project utilizes Evive, Arduino, and Dabble for seamless communication and control. During daylight hours, the system opens the window to allow natural light, turning off the electric lamp to reduce energy usage. As sunlight diminishes, the window closes, and the electric lamp activates. This automation enhances energy efficiency, saves costs, and reduces carbon emissions. The Smart Electricity Saver project exemplifies sustainable practices and contributes to a greener future.
