Flush Finder

Flush Finder is an IoT system designed to monitor and manage restroom availability and status in real time, targeting high-traffic environments such as schools, offices, and public facilities. The solution integrates both hardware and software components: distance sensors connected to an ESP32 microcontroller detect occupancy and usage conditions, while real-time communication is handled through the MQTT protocol, enabling efficient and low-latency data transmission. On the software side, a mobile application built with React Native allows users to check restroom availability remotely, while staff can update statuses such as maintenance or cleaning. The system was designed with a focus on real-time communication, scalability, and efficiency, delivering a practical IoT solution that bridges physical devices with a user-friendly digital interface.
