Weather stations are a popular project for experimenting with various environmental sensors, and for wind speed and direction the choice is usually a simple cup anemometer and wind vane.

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need any ...

An ultrasonic anemometer can measure these shifts between multiple sets of transducers and use them to reconstruct wind speed and direction. "By measuring sound travel time differences both ...

If you place your weather station in an alley, you could very well get a wind tunnel effect on the anemometer, resulting in erroneous wind data. Your weather station should have good "fetch", or ...
