6 Measurement Output
Measurements are transmitted in accordance with UMB binary protocol (Factory Settings).
You can find an example of a measurement request in different protocols and a complete
summary of the list of channels in the Appendix.

6.4 Air Pressure
Sampling rate 1 minute
Generation of average value 1
– 10 minutes
Unit hPa
Request channels:
UMB Channel Measuring Range
act min max avg Measurement Variable (float32) min max unit
300 320 340 360 Absolute air pressure 300 1200 hPa
305 325 345 365 Relative air pressure 300 1200 hPa
Note: For the correct calculation of relative air pressure, the altitude of the sensor must be
entered in the device configuration (see Figure 11 on page 32). The factory setting for
altitude is 0m; in this way both measurement variables deliver the same values.
