heal.abstract	The effect of humidity on tin-oxide thick-film gas sensors has been studied in the case of carbon monoxide, methane, methanol, butane and propane. The results are qualitatively explained under the assumption that water molecules dissociate on the tin-oxide surface and produce hydroxyl species capable of acting as electron donors. Moreover, palladium and vanadium, when used as additives, affect the overall behaviour of sensors in the presence of water vapour. To reduce the effect of humidity, thin organometallic films have been deposited on top of thick tin-oxide-based sensors in order to act as filters. The results show that both the sensitivity of these sensors and the effect of humidity are decreased. © 1995.	en
