Abstract

The present invention relates to faucets of the type used in sinks, lavatories, urinals and the like. Typically these faucets are made from metal or plated plastics and are electrically conductive. A module affixed to the outlet end of the faucet senses temperature or other fluid properties and generates a signal. A valve controller receives the generated signal and positions a control valve accordingly. The generated signal is communicated from the module to the valve controller by passing the signal along the conduit itself.
