With growing awareness of water conservation, more and more public buildings, commercial facilities, educational institutions, and healthcare facilities are paying closer attention to water efficiency. In addition to adopting water-saving fixtures and optimizing water supply systems, reducing water waste caused by human factors has also become an important part of effective water management.In daily use, traditional manual faucets require users to turn the water on and off manually. If users forget to shut off the water, fail to close the faucet completely, or leave the water running while washing their hands, unnecessary water consumption can easily occur.
