A catalytic sensor has been widely used for methane detection. Its nonlinear characteristic has lowed the accuracy of the methane detection.Due to the variance parameter of the sensor,the dynamic correction of nonlinear characteristic is very necessary for the accurate detection. A kind of neuron-network model,Adaline model, has been introduced in this paper. The function of intelligent learning in neuron-network is very useful for the process of the nonlinear characteristic of the sensor and has much increased the accuracy of methane detection.
