The classroom energy-saving system leverages the campus card for efficient management. The goal of this project is to create a system that uses an IR sensor to count the number of people who have visited a location, recognizes human presence using a visitors counter, and displays the number of visitors who have switched appliances. Nowadays, The main issue addressed by this project is energy waste in classrooms that people deal with is electricity waste. Even when no one is in the classroom, fans and lights are turned on in schools and colleges. This occurs as a result of the pupils' carelessness in failing to quickly turn off the electrical appliances. A system based on the microcontroller TM4C123GH6PM, temperature sensor, light-dependent resistor, and RFID tag/reader is suggested to implement this. The way the system is built ensures that
