Abstract
A sensor device comprises at least one transducer and a sensing material disposed on the transducer. The sensing material adsorbs or absorbs an amount of analyte (e.g., a target gas) that depends on a temperature of the sensing material and a concentration of the analyte. At least one detector is arranged to measure responses of the transducer to sorption or desorption of the analyte in the sensing material while the sensing material is heated and/or cooled according to at least one temperature profile. The device also comprises a humidity sensor that is arranged to detect a humidity level of the environment or sample containing the analyte. A processor or controller is programmed to determine the quantity (e.g., concentration) of the analyte by comparing values of the transducer measurement signals to reference data indicative of expected or pre-measured responses of the transducer to known concentrations of the analyte at the same humidity level as indicated by the humidity sensor while the sensing material is subjected to the same or similar temperature profile.
