Abstract: A gas sensing device for sensing a target gas in a gas mixture comprises: a measurement module configured for obtaining a sampled measurement signal, the sampled measurement signal being responsive to a concentration of the target gas in the gas mixture; a compensation module configured for compensating the sampled measurement signal using an offset information to obtain a compensated measurement signal; a processing module configured for detecting a sample of the sampled measurement signal, which sample fulfils a set of one or more criteria, and wherein a first criterion of the set of criteria is fulfilled if, according to an evaluation of the sampled measurement signal, the sample is associated with a concentration of the target gas below a threshold, and updating the offset information based on a sample which fulfills the set of criteria.
