Operation
After the Kombi-LoRaWAN is successfully installed, it operates on its own. However, there are some
considerations that are good to know when using the Kombi-LoRaWAN.
RHT measurement
Temperature is given in °C. Humidity is given in %RH.
TVOC measurement
An auto calibration is necessary for the TVOC sensor. A prolonged exposure to high TVOC concentrations
will affect the baseline of the sensor and the sensor will give incorrect readings until the baseline is
corrected. The auto calibration can work properly only if the Kombi-Sky is exposed to a fresh air at least
some hours after the prolonged exposure. TVOC concentration is given in ppb.
dP measurement
The pressure difference between the outlets is measured using the air flow. The direction of the air flow
determines the sign of the reading. If the outlet in the left-hand side is in higher pressure than the outlet
in the right-hand side, the reading is positive and vice versa. The pressure difference is given in Pa.
CO2 measurement
An auto calibration is necessary for the sensor. Without it, the sensor will drift over time and eventually
give incorrect readings. The auto calibration can work properly only if the Kombi-LoRaWAN is exposed to
a fresh air at least some hours during each week. In practice, the room must be unoccupied, and its
ventilation must be switched on. Concentration is given ppm.
Monitor menu
In MekuWin Mon-menu, you can monitor the measurement readings. The sensors are kept continuously
on. The values update at the rate the sensor can produce new readings.
Information about LoRaWAN is also displayed to help with potential connection issues.
Cal menu
The calibration menu settings are only for the manufacturer use. They are not explained in this manual.
