Capturing measurements from motherboard sensors is possible in a variety of environments, but it carries the risk of compromising such data. The safest way to access sensors is to directly access them using UEFI BIOS technologies, bypassing the operating system (OS). This paper examines the mechanisms for accessing motherboard sensors, as well as ways of transferring this information to the OS.
