Abstract: A sensor assembly for controlling a flow of water through a faucet includes a shank and a head. The shank is configured to pass through an aperture in a wall and terminates at a flange at a first end of the shank. The head is configured to be coupled to the shank. The head includes a base, a top portion, and circuitry. The base has a first side configured to be supported by a first side of the wall and a second side configured to interface with a first side of the flange. The base includes an opening configured to receive the flange and a hole configured to receive a portion of the shank. The circuitry is configured to be positioned between the cover and a second side of the flange opposite the first side of the flange. The circuitry interfaces with the second side of the flange.

Abstract: A sensor assembly for controlling a solenoid valve, the solenoid valve controlling the flow of water through a faucet, is described. The sensor assembly includes a head including a bottom portion configured to be supported by a wall and a top portion. The sensor assembly also includes a proximity sensor including a transmitter and receiver. The transmitter projects a beam into a detection zone. The sensor assembly also includes processing electronics configured to cause the solenoid valve to open in response to a receiver detecting a reflection from an object in the detection zone.
