| Abstract: | In this paper, the development of a carbon dioxide concentration detection system is introduced. Sampling and amplifying of the signals are completed by NDIR absorption and chopper technique. Measurement precision is improved by software compensation. It can continuously detect carbon dioxide and breath rate in real time. |
| Keywords: | carbon dioxide infrared spectrum absorption side stream compensation |
