Toilets are an essential amenity for maintaining good hygiene and sanitation, but the buildup of unclean emissions and frequent use can lead to poor indoor air quality. This project aims to develop an IoT-based toilet system that uses sensors to detect air quality and alert cleaners or owners when it is time for cleaning. The system consists of a microcontroller connected to air quality and motion sensors. A cloudbased algorithm analyzes the data to determine when cleaning is needed, while an exhaust fan maintains a comfortable environment and energy efficiency. The system can also integrate with a mobile app to check occupancy and air quality. By improving cleanliness and air quality in public/private toilets, this project can enhance user experience and reduce the spread of infections.
