Moen’s new MotionSense technology utilizes advanced sensors to detect movement in two sensing zones, setting water flow in motion as if on command. The water sensor at the top of the faucet starts and stops water flow with a simple hand movement above the faucet, while the ready sensor near the base of the faucet identifies when an object - such as a cup or hand - is placed beneath the spout. It runs water for as long as that item remains in range and automatically shuts flow off as soon as the object is removed from the sensing zone. The Arbor pulldown kitchen faucet is the first Moen faucet to offer MotionSense.
