Pet bowl having integrated sensing

Abstract

A pet bowl is provided that comprises a housing defining a water container, a proximity sensor located proximate to the water container, the proximity sensor having conductive circuitry comprising a first circuit made of a first metal and a second circuit made of a dissimilar second metal, and a controller processing signals received from the proximity sensor, the controller selectively switching the conductive circuitry between a first configuration operating as the proximity sensor to sense water contained in the container and a second configuration operating as a thermocouple to sense temperature proximate to the water container.
