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:

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.

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.
