摘要： PROBLEM TO BE SOLVED: To provide a power-saving carbon monoxide gas sensor having only a remote possibility of detecting hydrogen as a carbon monoxide gas and capable of detecting a carbon monoxide gas with superior quantitative property.
SOLUTION: The semiconductor-type carbon monoxide gas sensor is constituted in such a way as to set temperature of a membranous oxide at least at three temperatures (1)-(3) by controlling electric power of a heater for heating the membranous oxide, and to periodically change the temperature of the membranous oxide at the three temperature. The temperature (1) is an intermediate temperature for detecting a gas from the resistance value of the membranous oxide and is between 100°C-150°C. The temperature (2) is higher than the temperature (1) and is a high temperature for cleaning the surface of the sensor. The temperature (3) is lower than the temperature (1), is a low temperature for detecting whether a detected gas is a carbon monoxide gas or another gas from the resistance value of the membranous oxide, and is lower than 90°C.
