| Abstract: | This paper presents the total design of a NDIR based CO2 concentration detector.We substitute a new infrared detector for the traditional electrochemical sensor.We employ the advanced neural network algorithm to compensate the negative influence of pressure on the test of CO2 concentration.We establish a non-linear pressure compensation model.We demonstrate its preponderances in the measurement accuracy and measurement scope with experiments and large amount of test data. |
