Abstract
The responses of several tin oxide based sensors to contaminant gases, such as methane, carbon monoxide and hydrogen, are shown to be greatly affected by the oxygen concentration in the ambient atmosphere. A model is described which explains the observed results. At low oxygen concentration (4 are observed.Keywords
