Abstract
The optimal composition and ratio of semiconductor ethanol sensor gas-sensitive materials were determined experimentally. As a result of the study, a selective and sensitive semiconductor sensor was developed to monitor the amount of ethanol in gaseous mixtures, and its metrological parameters were studied. The optimum temperature for a sensor containing SiO2 / SnO2 + CuO, which provides the highest signal, is 350-375 0C. A change in temperature from the optimal value will cause the sensor signal to drop. The dependence of the signal (σgas/σair) on the amount of ethanol in the mixture in the range of 50 to 1000 mg / m3 of ethanol concentration is linear in nature.
