water censors

I assume you're talking about a float switch?  I've used them in a proof of concept mode, but don't have any actively in use today.  Mount them, hook them up to a breakout box, then watch the circuit for open/closed...pretty simple.

Waterbug. I have that hooked up and running. I think I did a thread on the hookup a while back.

I went the super cheap route and just ran a wire to my breakout box. Basically you take a 12 guage wire or whatever and put an audio jack plug on one end (to fit in the breakout box). I run the other end of the wire under my tank in the stand. On the part of the wire that is in the stand, every foot or so I stripped the wires and left them bare. So there are about 10 bands , each one inch length, of unprotected wire. If water ever gets in the stand it will fall onto the wire and close the circuit. The closed state can be detected by the apex. DOes this even make sense?

I tried a water sensor but you needed to have at least 1/8 inch of water to activate it. I want it activated if there is even a drop of water so that is why I did it the way I did.

 

Interesting design!  Just goes to show that sometimes a little ingenuity is just as good or better than buying an off the shelf product.

Potroast can you post some pics? Also did you she's 1 or 2 wires?

 

It looks like this:

"-----" represents the protected wires, with two individual protected strands in each.

"=====" represents where I stripped the two wires down to bare metal and separate them.

"--00" represents the audio plug

--00---------------------====-------------====-----------====--------------

When water falls on the stripped waters the circuit is closed and sends a signal to the apex.
