FIELD: physics.
SUBSTANCE: use: for controlling air quality, detecting volatile organic compounds. Essence of the invention consists in that the gas sensor for indicating volatile organic compounds consists of an ultraviolet light-emitting diode and an insulating substrate of polycrystalline Al2O3, on which platinum measuring electrodes and a sensitive layer are deposited, wherein sensitive layer is made in the form of deposited thin film of titanium dioxide with thickness of 10–50 nm on layer of nanocrystalline tin dioxide or zinc oxide.
EFFECT: technical result is reduction of operating temperature and power consumption when detecting in air volatile organic substances: formaldehyde, benzene.
