Touchless faucets are modern fixtures that allow users to turn the water on and off without physical contact. They use sensors to detect hand movements, making them convenient and hygienic, especially in public restrooms. This technology helps reduce the spread of germs and saves water by automatically shutting off when hands are removed. These faucets are often powered by batteries or electricity and can be found in various settings, including homes, restaurants, and commercial buildings. Many models come with adjustable settings for water temperature and flow, enhancing user experience while promoting cleanliness and efficiency in water usage.
