Abstract
The gas measurement device includes a filter having a plurality of openings, each opening being variable in size, an adjustment mechanism configured to vary size of the plurality of openings, a first gas sensor configured to detect gas molecules passing through an opening of the filter and output a first measurement value corresponding to the detected gas molecules, and a second gas sensor configured to detect the gas molecules passing through the opening of the filter, output a second measurement value corresponding to the detected gas molecules, and detect gas molecules of a gas species different from the gas molecules detected by the second gas sensor.
