Research on Temperature Compensation of SO2 Gas Sensor Based on RBF Neural Network

SO2 electrochemical gas sensor is vulnerable to the impact of environmental temperature;thereby its accuracy is limited. In order to overcome this shortcoming, the paper proposes a new temperature compensation method based on RBF neural network, which is realized with MATLAB 6. X program software. The result of experiment indicates that the maximum error of the sensor outputs may be up to 20.0 percent before temperature compensation. After the adoption of the temperature compensation method based on BP neural network, the maximum error is reduced to 1.44 percent, even down to 0.12 percent through the compensation based on RBF network. Therefore this way has a better effect on the temperature compensation, which proves that the SO2 electrochemical gas sensor may have a higher accuracy and temperature stability after compensation.
