Thank you for your question! With our Touch2O.xt hands-free faucets, the faucet itself is the sensor. When you place your hand within a few inches of the faucet (spout, body, or handle), the water will turn on. The water will then turn off when you remove your hand from the sensing field. You can also turn off the hands-free feature, so that the faucet turns on and off by touch.
