With the function block Wind Gauge, the frequency input from a wind speed sensor can be converted to a wind speed value
Please note that only inputs with frequency counter functionality can be used.
If the wind sensor is connected to a Digital Input of the Multi Extension Air, the wind speed is transmitted every minute. As a result, the value for calculation must be divided by 60!
