Linear temperature microhotplate gas sensor array for automotive cabin air quality monitoring
چکیده انگلیسی

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.
