Increased Selectivity of Sensors based on Sno2 To Couple Alcohol in the Air

Abstract

The increase in the gas sensor sensitivity is obtained by doping gas sensing elements based on doped SnO₂ by impregnating Pd. For personnel life safety in chemical, mining, metallurgical and other facilities, as well as in everyday life and for environmental monitoring, it is necessary to use sensors toxic and explosive gases. Such devices should provide a selective response to certain components of the gaseous medium which shaws highly reliable and reproducible results. Touch elements of such systems must have the highest possible sensitivity, selectivity, stability properties and processability in production. In case of burglar, alarm and gas detectors must also have miniature for stealth, low power consumption to increase battery life and resistance to mechanical stress. The presence of these devices, such as sensors of gas leakage in every house increases the safety of human life.
