I came across this and orders one. It monitors temp, humidity, door opening, lights, and motion. It's called Elertus. You can monitor everything in real time from anywhere, and it sends you alerts if temps or humidity power failure or a breach in the room. It's around 200 but I found one on eBay that was refurbished with a full warranty for 150, it takes a AA battery and last a full year. I like the fact that if someone were to enter the room it will alert me. Check it out and I will post updates to how well it works after I get it next week. http://elertus.net I'm excited about this product.
