Answer:

Infrared thermometers measure temperature by sensing the infrared energy which every material or object with a temperature above absolute zero (0 °K) will radiate. In the simplest configuration, a lens will focus the infrared radiation onto a detector which in turn will convert this energy into an electronic signal.
