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 short focus optical sensor mounted adjacent the sink which directs an infrared ray toward a user's legs for detecting the presence and absence of a user in the immediate vicinity of the sink. 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 for interconnecting the optical sensor to the adjustable clamp. The optical sensor is electrically connected to the on/off mechanism, via a conduit provided in the ball-and-socket flexible connector, 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.
