Effect of temperature, pressure and humidity on carbon dioxide concentration—simulation study

The growing application of infrared carbon dioxide (CO2) sensor now needs an accurate and precise measurement of human respired CO2 concentrations. CO2 concentration measurement is influenced by a number of environmental parameters. The objective of this study is to perform a simulation study on the...
