Abstract
The invention discloses a method for measuring a semiconductor gas sensor based on virtual alternating current impedance. The method comprises: combining measurement parameters of virtual measurement frequencies in a first predetermined range and virtual parallel capacitance values in a second predetermined range, and measuring gas with known concentrations at each characteristic quantity among nine characteristic quantities in the case of each combination; obtaining multiple characteristic values corresponding to the same gas concentration at each characteristic quantity after traversing all parameter combinations and all nine characteristic quantities; and selecting virtual measurement frequencies in a third range, virtual parallel capacitance values in a fourth range and one or several corresponding characteristic quantities as the finally selected measurement parameters for measuring the unknown gas concentration.
