Well, there are ALOT of options..
You got 1-wire for temperature.. thenyou use http://www.klein.com/thermd/for the software, get a usb or serial interface device for the sensors, then a couple sensors..http://www.hobby-boards.com/catalog/main_page.php has a good selection.. You can put a good system together for under a 100 i would imagine.
Then you've got the ready made systems: http://www.itwatchdogs.com/ http://embeddeddatasystems.com/page/EDS/PROD/HA/HA7Net with http://forums.cacti.net/about13526.html
The route I am taking is the 1-wire one, so I dont have alot of information ont he others.. the Ha7 product is just a ethernet device for the 1-wire interface. It communicates to the Cacti install of the monitoring server.

Hi all, I have a situation like this: Our little server room is always on. It has an air conditioning unit, but barely enough. So sometimes during weekend, the temperature could reach unhealthy level, like 29 degree Celsius. Currently, there's no personnel to monitor it 24 hours a day. I'm thinking of using a tool to monitor the temperature, and then send sms/email when it reaches certain threshold. Anyone has an idea? Could be software based or hardware one. Thank you.
Depending on the stakes, you might consider a solution from http://www.sensaphone.com/ They have a wide range of units at a wide range of costs. _______________________________________________
I was just getting ready to post this! They have great products. The sensors available are widespread... heat, cold, noise, motion, water, electric.... You program it to call a list of numbers... until one of those folks calls it back, it keeps trying. You can listen to the room from the phone. Really neat system and not a huge amount of money. Basically, it is a burglar system as well... can detect intrusions.
