| Abstract: | An experimental method was presented to calibrate dynamic characteristics of an infrared carbon dioxide sensor. A dynamic mathematic model of infrared carbon dioxide sensor was established. The design process of the dynamic compensation filter was given, and the various factors influencing the compensatory effect were discussed. To reduce the operation time and to improve the response characteristic of the sensor, a method of converting difference equation to recursive arithmetic was adopted. Experimental result showed that the application of the dynamic compensation filter can effectively improve the dynamic characteristic of the infrared carbon dioxide sensor. |
