Driver for a "switching" anemometer (wind speed gauge) that has an internal switch that is triggered during every revolution.
Represents a simple switching rain gauge
Driver for a wind vane that outputs variable voltage, based on the
azimuth of the wind. Matches the input voltage to the
dictionary lookup and returns the nearest azimuth to the voltage specified.
By default it will use look ups that match voltage outputs from the windvane in the Sparkfun/Shenzen Fine Offset Electronics with a voltage divider of 4.7kΩ / 1kΩ, as can be found in the SparkFun weather shield, or Wilderness Labs Clima Pro board.
