Hi,
Does anyone know here how to make an NPK sensor? I mean, what are its guidelines, processes, theories, and all the things necessary for it. Is it already available in the market? Not the analog one, but the digital one for discrete values. Thank you! And follow-up question: How does it deal with electric conductivity and electrochemical?
