IoT- Based Smart Classroom Automation System

Electronics &Communcation Engineering

This paper presents an IoT-based smart classroom automation system that enables real-time monitoring and control of electrical appliances such as lights and fans through a custom-built web interface. The system is powered by a centralized microcontroller (NodeMCU/ESP8266/ESP32) connected to a Wi-Fi network, acting as a communication bridge between user commands and classroom devices. Users can access the system via any internet-enabled device, including smartphones, tablets, or computers, to control a wide range of appliances remotely via web interface. The platform supports personalized automation scenarios based on specific schedules or events, improving energy efficiency, convenience, and classroom comfort. Robust encryption protocols ensure data privacy, while over-the-air updates keep the system secure and feature-rich. By integrating conventional appliances into a unified, web-controlled network, the proposed system enhances hygiene, accessibility, and automation in modern learning environments, offering a smart, user-friendly solution for classroom management.
