A classroom that senses presence, daylight and usage — then powers only what students actually need.
Occupancy sensors, daylight sensing and manual override form the physical layer. ESP32 / Arduino coordinates the response in real time.
Each occupied zone can independently control its LED and fan. Daylight reduces artificial lighting. Empty zones quietly switch off.
The technology disappears into the room. Students simply experience a comfortable classroom that wastes less energy.
A modular control layer can scale from a working classroom model to labs, offices and larger academic spaces.
