ABSTRACT:
A sensor assembly for use with a sink having a faucet hydraulically connected to an electrically operated on/off mechanism for controlling the flow of water from the faucet into the sink. The sensor assembly includes a fiber optic proximity sensor mounted adjacent the sink. The fiber optic proximity sensor directs a visible or infrared ray toward a user's legs, via a transmit fiber, and detects the presence and absence of a user in the immediate vicinity of the sink, via a receive fiber. The senor assembly also includes an adjustable pipe clamp for connecting the sensor assembly to the drain tube of the sink, and a ball-and-socket flexible connector. The ball-and-socket flexible connector provides a conduit through which the transmit and receive fibers are connected to the fiber optic proximity sensor, wherein the proximity sensor electrically connects with the on/off mechanism for controlling the on/off mechanism, so as to turn on the faucet when the presence of the user is detected and turn off the faucet when the absence of a user is detected. The sensor assembly further includes an adjustable connecting means for connecting the sensor assembly to a sink drain tube positioned adjacent to the on/off mechanism.
