In one embodiment, when the ultraviolet sensor 100 includes a plurality of unit sensors for detecting ultraviolet rays of different wavelength bands, the user can select a wavelength band of ultraviolet rays to be measured in the ultraviolet ray measurement application. On the other hand, in another embodiment, when the ultraviolet sensor 100 has a plurality of unit sensors for detecting ultraviolet rays of the same wavelength band, the user may be able to recognize that ultraviolet rays are actually irradiated from the light receiving surface 100a through the camera of the smart device 200 It is also possible to select only some of the unit sensors for measuring ultraviolet rays in the photographed radiation region.
