FIELD: measuring equipment.
SUBSTANCE: semiconductor methane sensor contains a dielectric substrate (1) and a sensitive layer (2) with metal electrodes (3) applied to its surface with a thickness of up to 0.2 mcm. The sensitive layer (2) is made on the basis of europium sulphide modified by the addition of samarium sulphide. The concentration of the additive does not exceed 25 moll. %.
EFFECT: sensor has a lower operating temperature for detecting methane in the ambient air.
