Which sensor to choose for measuring wind speed?

Question

Microcontrollers

Greetings to all who visit! Maybe someone had such a choice - please share your experience. So, the task is to make some kind of weather station (on an arduino, for example, or on Nucleo). With a humidity, temperature and pressure sensor, everything is more or less clear, but it is necessary to measure the wind speed. Are there any solutions? Thanks everyone in advance

Answer 1

The simplest option is to buy a ready-made weather station. It'll be the cheapest.
A more complicated option is to buy a ready-made anemorumbometer and calibrate it.
The most difficult option is to make an anemorumbometer yourself. And if everything is clear with the rumbometer, then the anemoment is a complicated thing. The impeller will rotate the rotor of the motor or encoder, from where the signal will be processed, but calibration will be needed. And you can calibrate such a thing only in a wind tunnel! Because no matter how you consider the model to be aerodynamic, it will be very far from real numbers.
Well, if there is a verified anemometer, you can try to calibrate it by running two devices side by side and accumulating enough statistics.
PS And there are also ultrasonic anemometers, but the math is even more complicated there.

Answer 2

Whistle and microphone.
