Abstract
The objective of this work is to develop a platform for a set of three conductometric sensors, able to deliver a controlled flow of indoor air samples in parallel to the three sensors. The system controls, on one hand, the air flow and, on the other hand, adds the capability of humidity control in two different ways: measuring humidity at the input and output, and stabilizing it through a filtering material. This way the performance of conductometric sensors can be enhanced, because one of the main causes of their low specificity is the cross-sensitivity to ambient humidity. The controlled amount of gas arriving at the sensors also avoids possible fluctuations in the sensor signals due to the air flow variations.
