Infrared radiation, though invisible to the human eye, is commonly used in which everyday household device?

Explanation

Infrared radiation is commonly used in television and other electronic remote controls, which emit an invisible infrared beam containing coded signals that a receiver on the device interprets as specific commands. Infrared radiation is also the basis for thermal imaging cameras, which detect heat given off by objects and living things. Because it lies just beyond the red end of the visible spectrum, infrared light is invisible to human eyes but can be detected with specialized sensors.
