Hi, :) i have arduino uno r3 and i want my arduino to detect the wind speed so i buy an encoder with optocoupler. The encoder will be fitted with propeller, so wind will drive the propeller and encoder will rotate. optocoupler used to read the signal from encoder. it will be look like this :
so, my question, is it possible to detect wind speed with that way and do i need other thing like schmitt trigger?
