There is a pressure sensor on the component board of the GMP231 that provides a live measurement of ambient pressure. GMP231 can compensate the CO2 measurement based on this pressure reading, or it can use a fixed setpoint. Using the GMP231’s own sensor is recommended for most applications.

If pressure compensation is turned off, GMP231 uses the default compensation value of 1013.2 hPa.
