Abstract

A sensor device for sensing CO2 comprises a hybrid sensing material and a transducer. The hybrid sensing material comprises at least amines and nanoparticles, wherein the hybrid sensing material has a property and is configured to change the property dependent on a current CO2 concentration in the surrounding. The transducer is configured to output an electrical sensor signal dependent on the property of the hybrid sensing material.
