There are currently no built-in sensors that can measure co2 levels.
I am not aware of any way to calculate this.
There are 3rd party external sensors that do what you want, but again - not built-in the phone.
문제
Is there a way on how to get CO2 from an Android Mobile using in-build sensors. Currently what I have obtained is the Current Speed, the Air Pressure, the Humidity and the Noise Amplitude by using the Environment Sensor.
If this is not possible, is there a way that I can calculate the CO2 (the value can be an estimate one)?
