cinci: Aww too bad about the displays. I'm sure I can find something. This PLC actually has a number of analog in's already so I'll just use those. Haven't got that part worked out yet though. I actually have a pressure transducer that I might use somewhere. The sensor I have is 0-5psi which is about 0-12ft. I think the analog in's are 12 bit which means 341 counts per foot. If I use one in my sump, 1 foot would be all that the level would change anyways so I would still have 341 points of resolution. I think it would be kinda fun to have a graph showing sump level. Then I could graph it next to humidity and temperature and get a good idea of where the water's going or the moisture is coming from . I'll get the rest sorted out first though . I could also stick a pressure transducer in my mixing bin to show how much water I have left. Too many ideas. I need my own house...

Midknight: Ha, yea right. Don't know about a seminar. If you're over this way you could come take a look. I'm sure if you wanted to do something like this I could point you in the right direction. I like doing this over buying a predesigned controller because I can make this one do whatever I want it to.

Here I am spending all this time on what controls the tank and what I really need to be doing is stocking the tank with more corals. My rocks are looking a little bare.
