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.
I'm looking for room temperature, not case temperature.
If your goal is simply to know when the server room is getting hot, the difference doesn't matter. All you need to know is that it is warmer than normal: The case temps will track room temps + some roughly constant number of degrees.
