I came over this wind sensor and interface.

@manu: looks like they have now a v2 of the board, form the web its not clear if this is just an improved version or another product. Do you know?

.. and - would be great to have a wireless transfer of the readings from the sensor to the board.

Dont know about the board, I think I'll buy the code and modify it.

It should be easy to use an arduino board with wifi, and modify the code. You will however still need the arduino board to be at the masthead. And it will still need power.. I'll try to add two relays and wifi, then run only power up the mast. The relays will be for navigation and anchor lights. 
Then i can run all lights at the masthead plus the wind sensor/ relay board off the same power cable, and control the relays and the wind sensor over wifi.

This is an old post but I can not restrain myself from adding a very simple and cheap wind sensor for a weather station. I followed the instruction from Chapter 6: Outdoor Weather Station in the book "Raspberry Pi Blueprints" ISBN: 9781784392901.

They use replacement parts for Maplin Weather stations such as https://www.maplin.co.uk/p/maplin-replac...96fy-n82nf and https://www.maplin.co.uk/p/maplin-replac...96gy-n81nf and an arduino. The arduino code could easily be modified to output nmea sentences.

Similar to the Peet wind sensor, the Maplin parts work with reel switches but at a signficantly lower quality and resolution (and price since it cost around 10£ in total!!!)

doesn't look like they deliver to US
i have been looking for a cheap instrument to test with..

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?

Hi Jim!

Yes, you're right. I had a friend in UK receiving the web shop orders I did in Maplin's web site. Sorry about not mentioning that.

One other option could be to use the rtl_433 library (https://github.com/merbanan/rtl_433) and find another weather station anenometer in the long list of compatible devices.

There used to be talk of having Openplotter count these sorts of pulses. I don't know if that's on the road map anymore or not.
