This is something I want to look in to for our little server room. It has gotten to the point where it gets really hot without the aid of air-con (temp unit in there currently, fixed unit is half way through being installed).
So temperature monitoring is essential, flood detection would also be hugely useful as we are at risk.
Whatever the solution, it would be nice if there were some generic digital/analogue inputs as well - one of the downsides to the aircon unit is that it relies on a pump to remove water from it's drain (as there is no drainage available vertically) - it would be cool to be able to monitor this somehow, although I haven't quite worked out the best way yet (the most reliable solution I think would be a junction in the pipe somewhere with a float and a microswitch to detect water build up), although I'm certain there is a reasonably simple solution.
I had the idea of using an Arduino combined with an ethernet module and SNMP stack (there is one available for the Arduino) so that it can be monitored with our existing monitoring tools. This is certainly the most interesting and coolest solution, although whether I should trust something of such importance to a home-brew project, I am unsure.
Is there something reasonably cheap out there that can match this brief?
