Hello Fernando. I would like to probe ph and density and the question is if I need the driver read the SD, and because it is not yet been able to solve the problem of the sd. And also i would like to know what type of ph probe density and can I buy or where to buy to have no problem to the time taken to load the code.
I have tucked away in the page that told me to do, but there are several products. Can you tell me exactly what would be the materials i need? For PH and density of water.
