Dear Sir, I wish to manufacturer Ph Meter both simple and microprocessor based. I kindly request the technical persons to help me in providing me the technical details like circuit digram and programme source.
The 80PH51A has a Ph sensor built it.
Have you done anything at all to get this done? If this is homework, you must inform your teacher that you have no idea where to start (or admit that you are cheating...)
What a refreshing change - no demands this time!
and you want your design work done for free?
