Abstract : The principle of sensing of carbon dioxide using IR radiation is int roduced and a novel double2beam optical st ructure is presented in the paper. Based on the good abilities of RBF network such as nonlinear mapping , learning and generalizing , the mathematic model of IR carbon dioxide sen2 sor is established. A dynamic compensation filter is designed to improve the dynamic characteristic of IR carbon dioxide sensor. A novel IR carbon dioxide sensor with high performance is made. The ex2 perimental result s show that the above key techniques prompt the accuracy , real2time and reliability of IR carbon dioxide sensor efficiently.
