# This simple algorithm calculate difference between five time equidistant points during the rotation. The result is angular speed per time step. |

# Size of time-step could be varied depending on expected wind speed range to measure. |

# Algorithm should be expanded by Kalman filtering to minimize dependence on fast reading. |

# The measuring principle could introduce time-stamped reading to increase precision of measurement. It could be possible because the readings are not exactly time equidistant in real Linux word. |
