The heart of the system is an integrated water-powered LED light that changes color in line with actual water usage; going from green when water starts flowing and changing every 10L. Once 30L is consumed (around 4.5 minutes in), the light will urge users to hurry up by turning red.
This project provides the first implementation of time reversal (TR)-based diagnostic method in a real urban water supply system (UWSS) and develops a remote and automated monitoring system to control it.
