The Smart Classroom using IoT is a student-developed project designed to automate classroom facilities using basic Internet of Things (IoT) concepts. The system automatically monitors student entry and exit and controls classroom appliances based on occupancy.

The project uses entry and exit sensors to count the number of students inside the classroom. This count is displayed on an LED display in real time. When students enter the classroom, the system turns ON the fan and LED bulb automatically using a relay module. When all students leave the classroom, the appliances are turned OFF, ensuring efficient energy usage.
