Problems solved by technology
Because the semiconductor material in the ultraviolet enhanced silicon photodiode has an intrinsic absorption wavelength greater than the ultraviolet region, it is necessary to add a filter when detecting, so this kind of detector has the problem of low detection efficiency. Due to its complex structure, and higher manufacturing costs, making it difficult to popularize in daily use

Abstract
The embodiment of the invention discloses an ultraviolet light detection method and a mobile terminal. The mobile terminal comprises a processor and an ultraviolet sensor module, and the ultraviolet sensor module comprises a specific integrated circuit chip, an ultraviolet light sensor, a first communication interface, a detection window and a light splitting device. The ultraviolet light sensor is used for sensing ultraviolet light of a first frequency band in an environment from the detection window under the condition that the light splitting device is located in a first deflection angle range, and generating a first analog electric signal. The specific integrated circuit chip is used for converting the first analog electric signal into a first digital signal and determining the ultraviolet light intensity of the first frequency band in the environment according to the first digital signal. The first communication interface is used for sending the ultraviolet light intensity of thefirst frequency band in the environment to the processor. The processor is used for executing a corresponding operation according to the ultraviolet light intensity of the first frequency band in theenvironment. The mobile terminal can detect the ultraviolet light intensity in the environment of the first frequency band through the ultraviolet sensor module.
Description
technical field [0001] The present application relates to the technical field of sensors, in particular to an ultraviolet light detection method and a mobile terminal. Background technique [0002] The sun is the most important ultraviolet light source in nature. Due to the existence of the ozone layer in the atmosphere, ultraviolet light with a wavelength of less than 305nm is almost absorbed by the atmosphere, and ultraviolet light with a wavelength of 305-400nm is irradiated to the surface of the earth. Some specific wavelengths of ultraviolet rays have carcinogenic effects on human skin. [0003] At present, in order to detect ultraviolet light, the ultraviolet enhanced silicon photodiode is the most common device for ultraviolet photodetection. Because the semiconductor material in the UV-enhanced silicon photodiode has an intrinsic absorption wavelength greater than the ultraviolet region, it is necessary to add a filter when detecting, so this detector has the proble...
