This paper reports on characterization of tin dioxide (SnO2) sensors for methane detection in the air atmosphere and determination of the optimal temperature range to achieve high sensitivity. There were done two measurement of our SnO2 thick film sensor on two different temperatures (240st C and 380st C) and compared with commercial sensor Figaro TGS 822. It was found that the sensitivity of our SnO2 sensor is the same at both temperatures we tested. In comparison of our SnO2 sensor with the commercial sensor Figaro TGS 822 was found that our SnO2 sensor has not a very high sensitivity for lower concentrations, but the saturation level is higher. It means that our SnO2 sensor is able to determine accurately the higher concentrations than the commercial sensor. We were able to determine methane in the concentration range from 50 to 4000 ppm.
