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 :(
