114 47 The Smart Toilet Internet of Things D. Thoren, K. Andersen, and M. P. Eilersen DTU Network Technology and IT, Technical University of Denmark Every year clean water is wasted due to leaking toilets. A single toilet can leak as much as 1100 L/day (Source?) and many people are unaware or uncommitted to their toilet’s physical condition. This is why we are proposing a smart solution that detects leakages, overflows and potentially many more water-wasting issues. By embedding a sensor tethered to a microcontroller within the toilet, where leaking water flows, it is possible to detect even the smallest leaks before the waste becomes significant. The solution is designed to work as an IoT (Internet of Things) device working over WiFi, this way different setups can be made for different scenarios. The solution also is an intelligence adaptable to all toilet independently by its frequency the toilet is used. The sensor has broad applications, from being a single add-on unit for existing household toilets to large systems of toilets (campuses, dormitories, hospitals) to being a built in feature in future generations of toilets. Our prototype has been implemented using a Wi-Fi compatible Arduino microcontroller and water-contact sensors. By using MQTT, a light weight messaging protocol, and Amazon Web Services (AWS) we are able to host our IoT infrastructure in a flexible and secure way. This architecture makes it possible to store the data in a database, send out notifications to specific users and produce statistics of water consumption and toilet conditions. Over the course of work on this project, we envisioned countless extended functionalities offering out of the box solutions that could save significant amounts of water. We hope our description caught your attention and highlighted the issue at hand. WATER LAPTOP CONCEPT BACHELOR LEVEL COURSE / PROJECT
