FIELD: measurement.
SUBSTANCE: invention can be used for identification of mixtures of volatile compounds. Essence of the invention lies in the fact that the sensor device comprises a measuring transducer based on a photonic crystal or a set of quartz crystals, on top of which there is a sensitive porous dielectric layer of a plurality of nanoparticles in form of balls of different diameters, forming a matrix of pixels, wherein each pixel consists of two subpixels, wherein one subpixel is formed of a set of hydrophobic balls, and the other subpixel is formed from a set of hydrophilic balls.
EFFECT: providing the possibility of creating a compact, easy-to-use measuring device which is not sensitive to changes in the external environment, and in particular to humidity, as well as possibility of its multiple use.
