This page shows the current wind speed and temperature at our RC model flying club, the Geretsrieder Modellbauclub. The measurements are done by a Raspberry Pi and several simple sensors. The software is freely available, the hardware is easy to build. Read the project documentation.
NOTE: The system is currently flaky; if “no data” is shown, select a date in the past where it was known to work: 2018-06-26
