It was shown using PCA on the sensor. result of extensive studies of gas- sensitive properties of SMO. The thick-film sensors, prototypes and the array’s components, were fabricated on the basis of commercial sensor platfor...

Operation-temperature dependence of the sensitivity. ambient gases does not show any systematic variation. All these results mean that the binders affect the sensing characteristics of WO -based gas sensors mainly through the modification of chem...
