Abstract
A device and process monitor a spatial area for a target gas. A sensor of the gas detection device used has a detection variable (ΔU) that is affected by the concentration of target gas. A detection variable sensor measures this detection variable (ΔU). The influence of a slower influencing variable and of a faster influencing variable, on the detection variable (ΔU), are computationally compensated to determine an influence-corrected detection variable (ΔU). Depending on the influence-corrected detection variable (ΔU), the target gas concentration is determined. For computational compensation, the time course (Dr[ΔU]) of the respective influence of the two influencing variables is estimated, for which a measurement value series from the detection variable sensor is used. The time course (Dr[ΔU]) is determined in such a way that the change per time unit of the influence lies within a given change tolerance band (Dr'[ΔU], Dr′[ΔU]) for this influencing variable.
