Water in what sense? Flood? Humidity? Plenty of humidity sensors. I have a rain sensor which has an ADC converter built in so when it's wet/dry it just outputs high/low which is easily read on the Pi GPIO. Search eBay for Arduino rain or moisture sensors and see if the idea of them makes sense for you. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

Water as in flood. We've had our A/C drain plug and spit water on the floor more than once. I did do a quick search after I posted and it seems most of them are used for moisture in soil. --------------------------------------------- Give me liberty or, I dunno, something.

Well who would believe that someone already did most of it? I figured that was the case but was too lazy to look until now! --------------------------------------------- Give me liberty or, I dunno, something.

There you go then! But I believe the soil moisture sensors can be used to detect water as a wet/dry variable rather than percentage of moisture. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

That may be what I go with, I'll try making this one first. The ones you buy just look better. --------------------------------------------- Give me liberty or, I dunno, something.

That's what I've got http://pages.ebay.com/link/?nav=item.view&id=281371131769&alt=web You could just remove the sensor plate, since its basically just a load of metal tracks that get bridged by water to make a circuit, and run two wires to the floor where the water will be. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

Hmm, so if any of that gets wet it registers right? That might work just fine. --------------------------------------------- Give me liberty or, I dunno, something.

Look what this guy made! Our farm isn't that big but this would still be pretty useful! --------------------------------------------- Give me liberty or, I dunno, something.

Yeah if you wet your finger and touch the plate it registers. Or put a drop of water on it. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘

Well you encouraged me to actually setup the rain sensor. ┌─────┐ │ │ │ ┌─┐ │ │ │ │ │ │ └─┘ │ │ │ │ ┌─┐ │ │ │ │ │ │ │ │ │ └─┘ └─┘
