Abstract: 

Moisture adsorption-desorption by silica porous glass wafer with a built-in conductive phase on the graphite base was investigated. The phenomenon of hysteresis was discovered in the dependence of the resistance of porous glass on changes in ambient temperature. An explanation of this phenomenon was proposed. The temperature ranges for its minimization were estimated. The ways of intellectualization of such kind of sensors using microprocessor techniques was demonstrated. The usage areas of such sensor were specified.

Keywords: 
humidity sensors, porous silica glass, sorption hysteresis.
