infrared thermometers
Forehead fever scanners
Infrared thermometers measure temperature without physical contact by detecting thermal radiation emitted from a surface.
A sensor converts infrared energy into an electrical signal, which is displayed as a temperature reading.
They're used in medicine The nurse used an infrared thermometer on my forehead, cooking, and industrial settings where touching the target is impractical or dangerous.
