Abstract
A gas sensor detects carbon dioxide, for example for use in air-conditioning systems. The gas sensor is based on a field effect transistor construction. It has a polymer-based material sensitive to carbon dioxide as gas-sensitive layer. The material has a cross-sensitivity with respect to air humidity. The influence of humidity is compensated for by using the signal of a humidity sensor.
