9.Public Toilet Usage & Hygiene Analytics

Project Overview:

The Public Toilet Usage & Hygiene Analytics system is a smart city solution designed to significantly improve the management, cleanliness, and public health standards of urban public restrooms. This project deploys a network of discreet IoT sensors within public toilets, including Passive Infrared (PIR) sensors to detect occupancy, door switches to monitor entry/exit, and water flow meters to track toilet flushing and handwashing activity. Data collected from these sensors is processed by low-cost NodeMCU microcontrollers and then securely transmitted to a Firebase database. A Python-based analytics engine then processes this real-time and historical data to identify usage patterns, track cleaning schedule adherence, and detect anomalies that might indicate hygiene issues or potential maintenance needs. The core objective is to provide facility managers and cleaning staff with actionable insights, enabling them to optimize cleaning schedules, deploy staff more efficiently based on actual usage, ensure hygiene compliance, and ultimately enhance the user experience by maintaining consistently clean and well-serviced public facilities.
