Automated Monitoring and Sanitization System Utilizing Internet of Things Technology to Manage Public Toilets

Public restrooms play a critical role in ensuring sanitation, yet they often suffer from unhygienic conditions due to inadequate cleaning practices. The proposed Internet of Things (IoT)-based automatic restroom sanitizing system addresses this pressing issue by automating the cleaning process and ensuring optimal hygiene standards. This system utilizes IoT technology, RFID devices, and sensors to monitor and manage the restroom environment effectively. The system tracks user activity in real time and initiates automated cleaning after a defined number of usage cycles, employing sensor-controlled water flushers and other mechanisms. Authorized personnel can monitor the system remotely through the Blynk cloud application, ensuring accountability and efficiency. Key components, including an RFID reader, IR sensors, ESP8266/32, water pumps, servo motors, and LCDs, work in tandem to deliver a seamless user experience. By automating routine cleaning tasks and providing real-time data monitoring, the proposed solution improves the quality of public restrooms and facilitates their efficient usage. The system achieves a 40% reduction in cleaning time and enhances hygiene through automated sanitization after five users. LCD displays restroom status, while a buzzer alert signals cleaning events, ensuring user awareness and efficiency. This approach not only enhances sanitation standards but also reduces the burden on janitorial staff, making public restrooms more accessible and hygienic for everyone.
