A sensor faucet includes a control assembly, a proximity sensor and a processing unit. The proximity sensor is configured to radiate a radio wave, receive a reflected radio wave, and output a sensing signal according to the reflected radio wave. The processing unit is electrically connected to the proximity sensor and a solenoid valve, and is configured to output a control signal according to the sensing signal. The sensor faucet is configured to perform: determining whether a voltage in response to the reflected radio wave in a second continuous number satisfies a predetermined condition when a first continuous number of the reflected radio wave exceeds a first threshold, operating the solenoid valve if the predetermined condition is not satisfied, continuously determining whether the second continuous number of the reflected radio wave exceeds a second threshold, and determining to output a sleep signal or a second control signal.
