Abstract

The present disclosure relates to a sensor unit for use in an air filter system which serves to separate at least one harmful gas from an air flow. The sensor unit comprises a first sensor. The first sensor comprises two electrodes and a material layer which connects the electrodes. The electrical resistance of the material layer changes when the material layer comes into contact with the at least one harmful gas. The sensor unit further comprises a processing unit configured to determine a time derivative of a change in resistance of the material layer of at least the first sensor and to generate an output signal based on a function of the determined time derivative. Furthermore, the present disclosure relates to a method for manufacturing the sensor unit.
