Weather station setup:

*Later changed to measure soil temprature at 0.01 m bellow ground (see metadata). **Installed at a later date (see metadata)

The sampling interval and storing is 1 minute. Data are acquired every hour over LTE.

The power supply is an important component of the weather station: photovoltaic modules and wind turbine are mounted on separated mast – 4 meters distance from weather station to prevent interference with measured parameters.
