Abstract
A sort of humidity sensor unit, comprizing main: a damper for logarithmic changes per changes in humidity and changes along with changes in ambient temperature as a temperature humidity sensor; and the oscillation circuit for output of AC signals at rated frequency to said humidity sensor unit; logarithmic compression circuit for logarithmic compression of the output signals of said humidity sensor unit; and temperature compensator for elimination of the signal change in said temperature contained in the polarity semi-wave signal of one of the logarithmic circuit outputs; featuring: said temperature compensator having te diode with the right-direction voltage changes in counter-ratio with respect to said temperature change, for formation of the said diode temperature characteristics for elimination of the main change.
