I have developed arduino based weather sensors for use with pypilot... They output nmea0183 so can be used with anything;

I'm working on a new version that integrates a small screen.
I would be very suspicious of any anemometer that uses reed switches for wind direction...
For direction, it relies on having the cups spinning to work. This means it cannot get wind direction if there is very low wind speed (to low to spin the cups) and it also cannot be very accurate when the cups are spinning slowly or at a non-constant speed. My sensors using potentiometer appear to have much better directional resolution and bandwidth. I also have barometric pressure.
How does it work in wind sheer?? Is it good enough for an autopilot?
