Level sensor on skimmer cup?

[subman]

I have seen someone do this but I can't find it again. I'm looking to add a level sensor to my profilux to shut off the skimmer pump and set off and alarm/ e-mail letting me know. Has anyone done anything like this?
Thanks

I think you saw it on Untamed tank build thread. If anyone he would be the on to ask.
