In the last few days I have been working on the first drafts for the anemometer of WinDIY_2. You can find the first information about this in the following project log: https://hackaday.io/project/180202-anemosens-sla-printed-anemometer

Since I've always wanted to build an anemometer anyway to be able to collect wind data for my weather station, I built the sensor modular so that it can also be used in other situations (e.g. a weather station).

I tried to make the wind sensor as compact as possible. The sensor electronics will be built into the 27mm thick shaft. Later I want to build an adapter board so that the wind data can then also be read via RS485 or USB. :)

I have almost finished the development. It will be used to sense wind direction and strength. This way WinDIY_2 can be pointed in the correct direction and shutdown/restarted if needed. 

Of course you can also use it as a windsensor for your weatherstation. :)

I have summarized a few details in the following video. You can also find more information here: https://hackaday.io/project/180202-anemosens-sla-printed-anemometer
