Classification and Application of UV Sensor
The human five senses are "sensors" with very complex and sensitive functions. However, most of the human five senses can only perceive information from the outside world qualitatively, but not quantitatively. In addition, there are many physical quantities that cannot be felt by the human. For example, they can perceive the visible part of the vision, but they cannot perceive the non-visible spectrum with a wider frequency domain. With the help of infrared and ultraviolet sensors, these invisible lights can be sensed.
