Positioning the relatively high-end SH50 18C, Sharp also prepared the ultraviolet detection function for it. With the help of the ultraviolet sensor in the upper right corner of the screen, you can test the ultraviolet intensity of the sun, which is divided into 0-5 grades to remind girls who love beauty to pay attention to sun protection at all times. Moderators have used various Sharp mobile phones with ultraviolet detection function. Personally, I think this function is trivial, and the accuracy and reference value of the test remain to be discussed. Some people think that if you want to know the intensity of ultraviolet rays, just look at the intensity of sunlight before going out. In fact, this concept is wrong. The intensity of ultraviolet rays is not equal to the intensity of sunlight. Even on cloudy days, there will be strong ultraviolet rays, even at night.
