Abstract

A gas sensing device for sensing one or more gases in a mixture of gases is provided. The gas sensing device (1) comprises: one or more chemo-resistive gas sensors (2); a preprocessing processor (3) configured for generating a preprocessed signal sample (PSS) for each of the signal samples (SIG); a drift correction processor (4) configured for applying a mapping function (MPF) to each of the preprocessed signal samples (PSS) in order to create a drift-corrected signal (DCS) sample for each of the preprocessed signal samples (PSS); a feature extraction processor (5) configured for extracting a set of feature values (FV) from each of the drift-corrected signal samples (DCS); a sensing result processor (6) configured for creating for each of the gases a sensing result (SR) for each of the sets of feature values (FV); a state processor (7) configured for determining a state (STA) of the gas sensing device (1); and an update processor (8) configured for providing updates (UPD) to the drift correction processor (4), wherein a quality value (QV) for each possible update action of a plurality of update actions is provided, wherein an update action processor (10) is configured for calculating the update (UPD) for the subsequent update step by applying the possible update action, which has a highest quality value of the quality values (QV) of the current update step, to the mapping function (MPF) of the current update step.
