The one of the example of the use of an infrared sensor is detecting the presence of humans trapped under collapsed buildings. Thus, option D is correct.
What are infrared sensor?
A radiation-sensitive optoelectronics component having a spectral sensitivity in the infrared wavelength range of 780 nm is known as an infrared sensor (IR sensor).
One application of an infrared sensor is to detect the presence of persons trapped beneath collapsing structures. Infrared sensors can detect infrared radiation emitted by a person.
These radiation-sensitive gadgets can also detect how much heat an object emits.
Hence, use of IR sensor is detecting the presence of humans trapped under collapsed buildings. Thus, option D is correct.
