Abstract
Embodiments of water sensors having multi-value outputs are disclosed. A water sensing circuit measures the impedance between two contacts of a water sensor and compares it with a reference signal. The impedance between two contacts varies depending on the wetness of the contacts, and so the sensing circuit may provide a measured wetness level. The water sensor may transmit measurements or other information wired or wirelessly. The water sensor may display indicia of measurements or other information via a display on a housing.
