Nanostructures based on zinc oxide were synthesized on ceramic substrate with interdigitated electrodes by spin-coating and low-temperature hydrothermal method. The sensor response to CO, CO 2 and O 2 was studied at room temperature under near UV light illumination. Gas exposure was supplied using metrological certified equipment. All samples showed no response to CO 2 . Layers based on zinc oxide nanowires are most sensitive to CO because of complex morphology and more effective adsorption of gas molecules. The obtained dependencies allow us to characterize the interaction of nanostructure based on zinc oxide with the main oxidizing and reducing atmosphere gases.
