Abstract: The CH4 sensitive semiconductor material was prepared from a high purity uonstoichiometrio n-type β-SnO2-x. A ceramic CH4 sensor was made from In, Pd-doped SnO2-x. The CH4 sensor was mounted on a miner's lamp, and the miner's lamp battary was used as the power supply. A new automatic methane warner has thus been developed and tested in some mines. When the CH4 sensor on the warner contacts with CH4 of over 1% concentration, the lamp automatically gives successive flash warnings.
