Sensor for measuring a gas concentration

Abstract

The disclosure relates to a sensor for measuring a gas concentration of a target gas in a sample of ambient air. The sensor comprises a first gas sensitive component comprising a first gas sensitive layer being arranged between a first pair of measuring electrodes, a second gas sensitive component comprising a second gas sensitive layer being arranged between a second pair of measuring electrodes and one or more heating elements to heat the first gas sensitive layer and the second gas sensitive layer. The first gas sensitive layer and the second gas sensitive layer comprise a metal oxide semiconductor. The first gas sensitive component is configured to measure the gas concentration of the target gas in a first concentration band and the second gas sensitive component is configured to measure the gas concentration of the target gas in a second concentration band. According to an embodiment, the sensor is configured to operate for both the measuring of the first concentration band and for the measuring of the second concentration band in a respective transition regime. The transition regime is situated between a perturbation regime and a saturation regime. The transition regime is characterized by a higher sensitivity to the target gas than the perturbation regime and the saturation regime. Further aspects of the disclosure relate to a corresponding method, a computer program product and an electronic device.
