Does anyone know of a cheap temperature sensor that will work with Linux? I don't need a fancy monitoring appliance, I just want a simple sensor that I can connect to one of my monitoring servers to let me know if the server room is getting hot
There is a good chance that lm-sensors supports your servers with no additional hardware needed. To configure lm-sensors, run 'sensors-detect' as root. If your cpu/motherboard is supported you will be able to read system temps directly either using SNMP or by scraping 'sensors' output.
