Design of Portable Gas Detector Based on DSP

摘要：

　　A new design method of gas detection system was given based on the new DSP processor TMS320F28335.The experiment system takes six metal-oxide semiconducter gas sensors as well as temperature and humidity sensors in comprising the sensor array module,followed the excellent detection principle how to choose,and choose CH4 and H2 as the test samples and use dual-BP neural-network with the temperature and humidity compensation function as the method to recognize and measure single gas and mixed gases respectively.The result shows that the measuring instrument has higher measuring accuracy and overcomes the shortcoming of other methods,and has important practical application value.
