1. A faucet comprising:
- a faucet body hub;
a manual valve handle movably coupled to the faucet body hub to control a manual valve, the manual valve handle being electrically coupled to the faucet body hub;
a spout coupled to the faucet body hub by an insulator so that the spout is electrically isolated from the faucet body hub;
a capacitive sensor having an electrode coupled to one of the faucet body hub and the manual valve handle; and
a controller coupled to the capacitive sensor, the controller determining which of the manual valve handle and the spout is touched by a user based on an output signal from the capacitive sensor.
