Abstract The humidity sensitivities of SrSnO3 and BaSnO3 were enhanced slightly By means of calcining their hydroxides, which were prepared by a coprecipitation method. The partial substitution of the A site element of the perovskite-type oxides with lanthanum was more useful for the enhancement of the sensitivity. The highest sensitivity was found in Sr0.95La0.05SnO3 among the specimens studied.
