FineOffset wind direction and speed sensors are cheap and easy to replace but not particularly accurate. Particularly the one that points the wind direction is known to be very "jumpy" (perhaps because it's too light) while simultaneously not picking the fine intermediate cardinal points as often as it would be statistically expected (meaning for instance than in the N-E quadrant it tends to accumulate readings in N - NE - E while NNE and ENE almost ever show up). There's a detailed study about this somewhere, I believe in SandaySoft forum, but it only takes a look at a daily windrose of readings to notice it.
My question then is: where to find a suitable replacement?
There is of course the Davis 6410, which I believe (correct me if I am wrong) can fit the WeatherDuino TX unit phone like jack without any modifications. It's nevertheless somewhat expensive (117 euros + 10 euros postage in the the linked offer) and according to a post somewhere in this forum not as durable as one would expect.
Does this leave us without options?
