2.3 Programming example
In the following programme example, the temperature, the air pressure
and the calculated altitude are shown.
In order for the altitude to be calculated correctly, the following line in
the programme example must be adjusted:
Replace the 1013.25 with the QNH pressure in hPa (the pressure at sea
level) at your location. Weather services can give you information on this.
sensor.sea_level_pressure = 1013.25
