FIELD: chemistry.
SUBSTANCE: sensor has a semiconductor base and a substrate. The semiconductor base is made from a polycrystalline film of indium antimonide doped with cadmium sulphide. The electrode platform of a piezoelectric crystal resonator serves as the substrate.
EFFECT: invention enables to determine content of nitrogen dioxide with sensitivity which is several times higher than that of existing sensors with significantly simple technology of making the sensor.
