School toilets often has three problems: electricity and water waste and smoke (illegal smoking)
by students. Our group developed a Micro:bit-based project to solve these problems.
The system has two functions:
- All fans and lamps are connected to motion sensors, and the ventilation and lighting system
are only switched on when the users move.
- Cigarette smoke sensors are installed in the restrooms, and as soon as smoke is detected, the alarm goes off and sends an alert to the manager at the same time
Future upgrade: Our team would like to upgrade the water supply with hand sensors so that water only flows when users put their hand to the faucet. At the same time, the water runoff from the sink will be used to irrigate the school garden.
