Hardware setup:

Use the signal generator to control pulse frequency Connect the pulse to the input of B&G Wind Create table Hz vs AWS Do the linear regression

-- Standard | U=A0+B0×f Wind Speed | U [m/s] Offset | A0 m/s ("starting speed") Gain | B0 [m] Output Frequency | f [Hz]

The data is summarized in this Google sheet

The result of linear regression: B0 = 0.96745 A0 = 0.99096

U = 0 if f < 0.04 Hz
