FIELD: measuring equipment.
SUBSTANCE: piezoresonance sensor contains a camera with a piezoresonator oscillation frequency generator, a piezoresonator and a frequency meter, the camera is equipped with a temperature changer and a temperature meter, connected in series with the information processing and storage unit, a unit for displaying the results of measuring the relative air humidity. The output of the frequency meter and the output of the temperature meter are connected to the first and the second inputs of the information processing and storage unit, and the piezoresonator electrodes are modified with a polyvinylpyrrolidone film.
EFFECT: providing the possibility of determining the relative air humidity in a wide range of temperatures, including negative.
