1. A faucet comprising:
- a spout;
a handle;
a touch control operably coupled to at least one of the spout and the handle;
a proximity sensor having an active state and an inactive state; and
a logical control operably coupled to the touch control and the proximity sensor, the logical control including;
a first mode, wherein the proximity sensor is inactive;
a second mode, wherein the proximity sensor is active; and
a controller operably coupled to the touch control, the controller determining which of the spout and the handle is touched by a user based on an output signal from the touch control, and wherein a first output signal change is detected by the controller when the handle is touched by a user, and a second output signal change is detected by the controller when the spout is touched by a user, the first output signal change being greater than the second output signal change.
