Among the many physical and chemical strategies used to make air pollution gas sensors for CO and NO2 monitoring, those employing multi-sensor arrays offer excellent selectivity, long lifetimes, low drift and low costs of manufacture. Targeting the two gases CO and NO2, new thick film sensor matrix was fabricated using the screen printing technology. With this purpose, undoped and noble metal-doped thick film SnO2 sensing layers deposited by screen printing technique upon rnicro-machined Si substrate have been characterised. The main objective in this study has been the challenging perspective to define a sensing layer type which allows a high quality monitoring and easy discrimination of low concentration of NO2 by an interfering species like CO, both present in the outdoor air. The experimental results reported in this work have shown that combining the sensor technology with a suitable catalytic element in the present case, gold, palladium and platinum, low concentration of NO2 can be revealed with a sufficient selectivity towards CO.
