What is the influence of pressure on the signal?

BlueInOnes are equipped with a pressure measurement. That means the signals of CO2 and O2 are pressure compensated.

What is the pressure range the BlueInOne could be used in?

It could be used between 0.8 and 1.3 bar (absolute). This means at an atmospheric pressure of approximately 1 bar, the sensor could be used at 0.2 bar negative pressure and 0.3 bar positive pressure.
