I'm interested in your project. I'd like to see a computer UI though, and eventually maybe like android, and/or iPhone/iPad. There are other things to monitor and control though. What I'd like to see is a complete solution for growers to monitor TDS, EC, Ph, maybe res temp as well. A GUI programmed so that you can set alarms for the Ph being too high or low (which there are hardware components that could be created. To adjust these automatically also. If you're interested let me know please. This is the simple ver. Of what I'm talking about. Creating a line of products is quite fathomable and marketing is one of my strong suits, if a finished set of products can be produced. I want to work with someone who wants to partner, or will end up hiring someone when funds become available.
