If you run a server room or have tons of computer equipment in your house you might want to keep track of the room environment. Invent Geek has made a Open Source Server Room Monitor project to help us do this on the cheap.

“The server room environmental monitoring system is a low cost high performance device with the same onboard features as commercial devices costing hundreds of dollars more. In addition to a low cost platform we will provide low cost sensors for many important devices to insure your equipment stays safe and sound.”
