The valve of a faucet equipped with a proximity sensor and a mechanism allows it to open and close in reaction to the presence of a hand or hands nearby. This type of faucet is known as a sensor faucet. Airports, hotels, and other public spaces all have sensor faucets. After detecting a hand close to the faucet, the proximity sensor in the faucet starts to flow water.

The sensor tap turns on the water when it notices such a movement. The water flow of this device is sensor-controlled is modified in accordance with how long the movement lasts. Since the water flow is immediately stopped when hands are taken out from beneath the sensor tap, this significantly reduces water waste.
