Sensor three-hole widespread deck-mount bathroom faucets let users start the flow of water through the faucet without touching it. This reduces the spread of germs and helps keep the bathroom environment clean. The faucets automatically turn off after a preset period of time to save water and utility costs and stop the sink from overflowing. Users cannot control the temperature of the water flowing through sensor faucets, so they must be preset to water temperatures that prevent scalding injuries. The hot and cold water supplies join inside the spout to provide water for handwashing and grooming tasks. Three-hole widespread deck-mount faucets install into a sink, counter, or horizontal surface with three holes where the outermost holes are 8" apart when measured from center-of-hole to center-of-hole.
