Smart home system solution with the goal of minimizing water consumption

According to EPA (United States Environmental Protection Agency) the average household's leaks can account for nearly 10,000 gallons of water wasted every year and ten percent of homes have leaks that waste 90 gallons or more per day. Common types of leaks found in the home are worn toilet flappers, dripping faucets, and other leaking valves. This study proposes the development of a smart home system for saving water in the toilet tank by using a controller that opens and closes the valve, detects water leaking and toilet overflow. When leak or overflow is detected, the device will perform the corresponding operation and indicate the type of error by lighting the specific LED (light-emitting diode). The process for measuring water level and leak detection as well as device implementation is given by this paper.
