High-Speed, Accurate Gas Recognition and Concentration Estimates by the Time-Division Method

摘要

There are increasing demands for gas sensors in various fields such as food, cosmetics and safety applica- tions, and a method is required which can recognize the existence of a gas quickly and with high accuracy, as well as a method to measure the gas concentration quantitatively. In the system proposed in this paper, the gas is recognized Resonator sensor. The sensor can detect various gases, but May require a long time, depending on the type of gas, due To its operating principle.
