Abstract
A gas sensor, for example for use in air conditioning systems, has a gas-sensitive layer that includes a material that is sensitive to carbon dioxide. The material has a cross-sensitivity to air humidity. This is compensated for by measurement at two different temperatures. The measured gas values are calculated together, with the assumption that the sensitivity of the gas sensor to carbon dioxide exhibits a different curve with the temperature of the gas sensor than the sensitivity to water.
