This touchless bathroom sink faucet uses an infrared sensor to start water flow automatically when hands are near and stop it when they move away. It is designed for standard sink installations and supports hot and cold water adjustment through a mixing valve beneath the sink. The zinc alloy body with chrome-plated finish is built for everyday use and resists rust in humid environments. A honeycomb aerator helps soften the water stream and reduce splashing. Battery-powered operation allows simple maintenance and tool-free battery replacement.
