Public restroom monitoring system

Abstract

The public restroom monitoring system not only addresses the health risks and environmental issues of unsupervised restrooms but also promotes sustainability and resource efficiency. By incorporating automated mechanisms and smart sensors, the system delivers a secure, hygienic, and enjoyable user experience. A motion sensor detects when a user enters the cabin, triggering an Arduino-controlled electronic lock to ensure privacy and safety. The system also features

automated cleaning initiated by pressing a button, which activates both the water trap and an odor- extraction aspirator, programmed with precise timing intervals to guarantee a clean and fresh cabin.

Outside the cabin, a residual odor detector monitors air quality, signaling a ceiling aspirator to remove unpleasant odors and maintain a pleasant environment. The system brings multiple benefits, including automated cleaning, which cuts down on maintenance costs, eliminates the need for constant manual cleaning, and ensures consistent sanitation. Furthermore, the system promotes energy efficiency and helps reduce water waste through controlled and precisely timed processes. It enhances the user experience by maintaining a clean, odor-free environment while reducing operational costs. The project demonstrates how automation can improve the long-term management of public restrooms, integrating advanced technologies for hygiene, odor control, and resource optimization, resulting in a sustainable, cost-effective solution that boosts user satisfaction and supports environmental goals.
