Human body emits Radiation

Question

Human being emits which type of waves and how to find that waves any possibility to detect this waves by Using sensors

Answer 1

Because of our body temperature, humans emit radiation in the Infrared range. At $37^\circ C$, humans emit infrared radiation primarily at a wavelength of $12\mu m$ or $0.000012m$. A large number of detectors can be used to measure this emission. This radiation emission is how heat-sensitive cameras can see people in the dark. There are many other examples as well of technologies that are used to sense, measure, or quantify the IR emission of humans.
