Come fare un anemometro

Come posso realizzare un anemometro con arduino programmando con xod

That depends on which sensor you are trying to read the wind speed from. The one described DIY Arduino Wind Speed Meter Anemometer Project - Geeky Gadgets you just need to do an analog read and convert to wind speed using math functions. Most of them I saw after a quick search for “Arduino anemometer” required additional hardware to convert sensor output to something the Arduino could handle.
