Description: 
The present work describes the experimental evaluation of an innovative gas sensor array for automotive cabin air quality applications. This integrated array presents as a main innovation aspect the simultaneous outputs, from a single chip packaged onto TO-12 socket, of eight different signals coming from a WO3 thin film structure heated in a linear temperature gradient mode, allowing an overall evaluation of gas sensing properties of metal oxide materials in a 100 °C-wide window, typically from 300 to 400 °C. Experimental results will be explained by means of PCA (principal component analysis) compounds identification for three different target gases of CO, NO2 and SO2 at different concentrations.
