Indoor air quality monitoring and control at home and in cars are essential for energy saving, especially for highly sealed passive buildings and electrical driven cars. The demand driven ventilation assures the optimum compromise between a good air-quality and energy saving. This paper describes a sensor system measuring temperature, relative humidity and CO2 concentration based on resistive and impedimetric sensors. A first system on polymer foil with Au-thin film resistors and interdigital capacitors (rh, CO2) demonstrates the proof of principle and enhances the capability of prior results with CO2 measurement.
