Read data from WH3080 wind sensor

I have a WH3080 with many issues but the wind sensor works fine. I saw a nice project (internet) where data can be read from a WH3080-like wind sensor with Arduino.
I want to try this out of curiosity. A guy that did this said he could read data every second.

Did anyone here try something like this? What is the protocol to read the data out?
Thanks.
