ABSTRACT:
A differential capacitive moisture sensor, relying for its operation on the time-varying couplings in two moisture-sensing regions to provide indication of presence of moisture, with selectivity of sensing surface provided by a shielding electrode, and with temperature information provided by a simultaneously-fabricated resistive temperature sensor. Various electrode connections and sensor electronics may be used.
