Abstract

A gas detecting system, device and method use a variable pulse voltage waveform to increase the temperature of a detecting unit of the gas detecting system so it reacts with gas molecules from a particular space, and outputs a sensing signal. A processing unit of the gas detecting system then performs calculations on the sensing signal, such that an analysis unit may determine the presence of a target gas in the particular space, and further the composition and concentration of the target gas within the particular space, thus providing a detection that is accurate, rapid and convenient.
