ULTRAVIOLET LIGHT SENSING

摘要

A method of measuring ultraviolet light includes observing an ultraviolet portion of ambient light with an ultraviolet light sensor, measuring an intensity of a visible portion of the ambient light with a visible light sensor, and estimating an intensity of the ultraviolet portion of the ambient light based on the measured intensity of the visible portion of the ambient light if the observed ultraviolet portion of the ambient light exceeds a threshold intensity.
