Journal of Atmospheric and Oceanic Technology, 1996 Abstract A common feature of all capacitance humidity sensors is their undesirable hysteresis effect due to the unequal adsorption and desorption of water vapor on the surfaces of their dielectric porous materials. To eliminate this error, an improved humidity sensor has been used composed of a commercial capacitive polymer sensor chip and an infrared (
