METHOD FOR DETECTING GAS CONCENTRATION

摘要

PROBLEM TO BE SOLVED: To provide a gas concentration detecting method of excellent response. SOLUTION: In a gas sensor element 1 for detecting the specified gas concentration in a gas to be measured, the sensor output after a predetermined time is estimated and the specified gas concentration is detected by using the time derivative A(t) of the sensor output Y(t) in the gas sensor element 1, and the time derivative B(t) of A(t).
