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.
6.1 Air and Dewpoint Temperature
Sampling rate 1 minute
Generation of average value 1 – 10 minutes
Units °C; °F
Request channels:
Measurement Variable (float32)
External Temperature Sensor
External Temperature Sensor
6.2 Wind Chill Temperature
Sampling rate 1 minute, computed on base of the average temperature
and average wind speed
Units °C; °F
Request channels:
Measurement Variable (float32)
6.3 Humidity
Sampling rate 1 minute
Generation of average value 1 – 10 minutes
Units %RH; g/m³; g/kg
Request channels:
Measurement Variable (float32)
6.4 Air Pressure
Sampling rate 1 minute
Generation of average value 1 – 10 minutes
Unit hPa
Request channels:
Measurement Variable (float32)
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.
