| Abstract: | The features were extracted through fast Fourier transform and the FFT radar plots of gas sensor dynamic responses were built.Founded by the FFT radar plots,the dynamic responses of microhotplate gas sensors to three kinds of flammable and explosive gases were studied modulated by total 96 modes including sine wave,triangular wave,sawtooth wave and rectangular waves,each with 6 periods,4 temperature amplitudes.The effects of temperature amplitudes,period and wave types on discrimination results were analyzed and a FFT radar plot based temperature modulation mode selection approach was proposed. |
| Keywords: | gas sensor temperature modulation mode selection Fourier transform |
