I am planning for my wind speed project. I need to read a pulse frequency from a rotation counter, but I have done some bench testing using a function generator & the node-red-contrib-frequency-meter node, and it seems to top out at about 20Hz. This seems to equate to approx 25-30mph, which isnt quite enough.
Any ideas as to what I could do instead ? Is there a HAT with a counter ?
Needs to be simple, I'm only an engineer
