Hello All.

I sure could use some help; if there is any to spare?

Thanks a lot for the pointers! But no fishy joked;-(

You haven't seen any PID controlled TEC circuits I could use to keep my 1
gallon Betta fish tank at the same temperature (approximately). I figured I
would also add a turbidity sensor to run for about an hour or two daily to
keep the debris on the bottom from collecting and stagnating the water.

I know this sounds like an over kill but experience is a good teacher. I was
going to measure the water temp and control functions on a 2 X 20 character
display. The sensor would be an LM34/35/AD590 encapsulated

Thanks for the links and advice. If you chime in please be my guest.

Cheers,
Ed
