WizardX asks: "At my new job we are in the process of starting to Do Things Right(tm). One of these things is putting the computer room (where the IT staff also resides), on its own cooling circuit. We want to monitor and track the temp and humidity in the room. The tracking part makes it more difficult. I really am not familiar with devices to do this. I plan on monitoring with MRTG, so a device that could plug into our network would be nice, but as long as it can dump the data to a computer (*nix or Windows, I really don't care) I will be happy. What have you seen or used?" I think the submitter is looking for something along the line of these devices, but maybe some of you have run into something better?
