Anemometer

Hi ,
i want to make an anemometer and done somtheing like that:DIY Anemometer: Wind Speed Sensor Device - Arduino Project Hub
How to convert the value that the dc motor gives to km/h?

connect a Voltmeter to the motor output and take the device out for a ride. Map Voltage to MPH in your car (as listed in the Q&A below the post in your link)

Do not double post.

The classic way is to do runs in both directions and average your reading, to cancel any ground wind bias.
