    How did you calculate the 50.74 ? const float WIND_RPM_TO_MPS = 50.748803; // divide RPM by this for meters per second in the USB Weather Board V3 firmware?

    The datasheets states that 1 click/s gives 2.4 Km/h or 0.67 m/s. Assuming 2 clicks per rotation: 1 Rotation/s corresponds to 1.3333 m/s now if you have RPM the speed should be (RPM/60) * 1.3333 m/s or RPM/45

    How did you come up with the 50.74?

No public wish lists :(
