Patent attributes
A sensor for detecting the presence of a liquid. The sensor includes a housing having a concave upper surface, a concave lower surface, and a peripheral wall connecting the upper surface and the lower surface, the wall extending above the upper surface and below the lower surface. A plurality of apertures are formed in the wall. A plurality of electrically conductive members extend above the upper surface and below the lower surface and are separated from one another by a gap in which a liquid can accumulate. The electrically conductive members are configured to generate an output signal when a conductive liquid comes into contact with the electrically conductive members and bridges the gap. An output connector is coupled to the plurality of electrically conductive members and is configured to carry the output signal.
