ABSTRACT:
A humidity sensing device comprising a solid electrolyte evidencing proton conductivity includes HZr.sub.2 P.sub.3 O.sub.12 or a composite comprising HZr.sub.2 P.sub.3 O.sub.12 /ZrP.sub.2 O.sub.7. The humidity sensing device is operative over a temperature range from 350.degree.-600.degree. C. The humidity sensor is operated by an impedance-type cell.
