In Linux, any device operations are abstracted as file read/write, read the content in the/sys/class/thermal/thermal_zone0/Temp File to get the Raspberry Pi CPU temperature.

This assumes that you already have the Raspberry Pi 2/b+, and that it is already installed. If not, I suggest you buy one, they are both cheap and fun.
Personally, I'd rather spend a little more money buying from Canakit. Their logistics quickly and reliably, plus their ready-to-go service is also very good.
