Cellar Dweller

I want to turn my cellar into a decent workspace but it's currently too damp. If you leave things down there the cardboard goes limp and metal slowly corrodes.

It may be that I have to resort to professional tanking of some kind, but as an opening gambit I'm going to try drying it out with a dehumdifier.

Emptying the condensate tank regularly is dull, but there's a connection for an external drain, so I've built a bigger tank out of an old 'Really Useful Box'. This complete with float switches to sense the level and a pump to push the water up out of the cellar into my garden.

This could have been managed with a very simple latching circuit, so it switched on once full and didn't switch off until empty. However I've got all the bits to do this with an Arduino. An added bonus is I can put it on the Internet, so it's now got Ethernet and a temperature/humidity sensor so you can look at a web page showing the current readings and how often it has emptied the tank.

It'll be riveting stuff.

Once I run a network cable down there.
