Can anyone suggest a CHEAP Wind Speed and Direction sensor that can be used to run in OPEN CPN, with raspberry pi or even better directly on my Android Tablet?
As Marine branded ones are super expensive, I am looking of corse for thouse cheap chinese ones, but seams all of them have RS-485 Modbus protocole, not NMEA 0183.
Like this ones:

Thanks for your help!

Take a careful look at what you are planning to buy, before you buy it. I checked the link above to see what the resolution of the wind direction sensor was, and it is "8 directions" Completely useless on a
boat. You will probably find that most of the cheap stuff will be like that.
If you want to
work with an Arduino and haven't before, I suggest starting with one of the
learning kits on Amazon, that includes a breadboard, a bunch of
electrical components, and sample projects teaching programming.

If you already have some basic
electronics knowledge and a basic understanding of C programming, you could skip that, but otherwise I think you would be
lost without it.
There is an opensource wind sensor you can build, but would probably cost as much as a
commercial one, and would require a 3d printer and some
electronics skills.

I have no personal experience with it, but NASA Marine (no relation to NASA) possibly makes the cheapest NMEA0183 sensor, and some do use it.
