An apparatus for detecting and reporting the presence of liquid on a surface has a detector unit that rests on the surface with the detector unit including at least one pair of spaced-apart electrodes for conductively detecting the liquid, with the detector unit resting on the surface via the electrodes, and with the detector unit further including a sensor that is directed toward the surface and serves for optically detecting the liquid. The apparatus also comprises an operations unit, with the detector unit and the operations unit being electrically interconnected.
