— Schools, especially classrooms, are using more and more energy, which often leads to a lot of wasted electricity because people have to manually control things like lights, fans, and air conditioners. To solve this problem, this project suggests an IoT-based energy optimisation system for smart classrooms that is aware of how many people are in the room. For real-time monitoring of classroom conditions like occupancy, light intensity, and temperature, the system uses sensors like PIR motion sensors, LDR light sensors, and temperature sensors. A microcontroller, like the NodeMCU (ESP8266) or ESP32, takes the data from the sensors and automatically controls electrical devices based on who is there and the weather. The system turns on the needed devices when the classroom is full and off when it's empty to save energy. The system also sends the data it collects to a cloud platform, which lets you monitor and analyse it in real time using web or mobile apps. The proposed solution makes better use of energy, lowers the cost of electricity, and requires less human intervention. It also helps create smart and long-lasting learning spaces by using IoT technology to automate energy management and make smart decisions.
