Educational institutions consume substantial electrical energy due to the continuous operation of lighting systems, fans, air-conditioning units, laboratory equipment, and various electronic devices. Efficient energy management is therefore essential to reduce operational costs and support environmental sustainability. This study presents an IoT-based smart energy saving system specifically designed for educational campuses to monitor, control, and optimize energy usage. The system integrates IoT sensors, smart meters, current sensors, and motion detectors to collect real-time data on power consumption, occupancy, and environmental conditions across classrooms, laboratories, corridors, and administrative areas. Using microcontrollers and wireless communication technologies, this data is transmitted to a central server or cloud platform for intelligent analysis. Automated algorithms make decisions such as switching off lights and fans in unoccupied rooms, dimming lighting based on ambient conditions, and regulating HVAC systems to prevent unnecessary energy wastage. A centralized, cloud-based dashboard provides administrators with visualizations, usage patterns, alerts, and predictive maintenance insights, enabling data-driven decision-making. The system also supports demand-side management by identifying peak usage periods and optimizing load distribution. By enhancing automation, reducing manual intervention, and providing actionable insights, the proposed IoT-based smart energy saving system not only minimizes energy consumption but also contributes to sustainability goals, lowers electricity expenses, and promotes an energy-conscious culture within educational institutions.
