Investigation of gas sensors for cabin air quality monitoring
Car cabin air quality monitoring can effectively be analysed using metal oxide semiconducting (MOS) gas sensors. In this paper, commercially available gas sensors are compared with fabricated MoO/sub 3/-TiO/sub 2/ and MoO/sub 3/- WO/sub 3/ thin films. The laboratory tests showed that the MoO/sub 3/ based sensors possessed comparable gas sensing properties. The MoO/sub 3/(75%)-TiO/sub 2/(25%) sensor has a response 74% higher relative to the best commercial sensor tested.
