Sensor faucets are modern fixtures that use infrared technology to detect hand movements. When a user places their hands under the faucet, the sensor activates, allowing water to flow without the need for manual operation. This touchless feature promotes hygiene by reducing the spread of germs. These faucets are commonly found in public restrooms, kitchens, and hospitals. They can help conserve water by automatically shutting off when hands are removed. Additionally, sensor faucets often come with adjustable settings for water temperature and flow rate, making them convenient and efficient for everyday use.
