There’s only a handful of truly innovative products at the InterZoo-Zoo and so far the Osmocontroller Digital from Elos is definitely one of them. The Osmocontroller digital is a patented water level sensor from Elos which uses a miniature heating element to sense whether it is submerged or emerged. The sensor itself is always warmed but when it is out of the water, it will get hotter than when it is submerged, prompting the controller to kick the tiny little sump pump which is included in the kit.
