Abstract

The invention discloses an ultraviolet index monitoring module. The ultraviolet index monitoring module comprises a probe chip and a signal processing circuit. The probe chip is used for making ultraviolet radiation subject to photovoltaic conversion to form a light current signal. The signal processing circuit is used for converting and processing the light current signal after conversion to acquire an ultraviolet index and comprises a low-noise transimpedance amplification circuit, an A / D sampling conversion circuit and an ultraviolet index calculation circuit, wherein the low-noise transimpedance amplification circuit is used for converting the light current signal to a voltage signal, the A / D sampling conversion circuit is used for converting the received voltage signal to a digital signal, and the ultraviolet index calculation circuit is used for calculating the ultraviolet index according to the received digital signal and a weighted value corresponding to an erythema effect spectrum curve. The ultraviolet index monitoring module can effectively achieve purposes like the miniaturization and integration, power consumption, sensitivity monitoring, reliability of functional modules on smart phones and intelligent wearing platforms.

Description

technical field [0001] The invention relates to an ultraviolet index monitoring module, in particular to a smart ultraviolet index monitoring module. Background technique [0002] Ultraviolet radiation has an important impact on human health. An appropriate amount of ultraviolet radiation can help the body synthesize vitamin D3, which is beneficial to human health. However, excessive ultraviolet radiation will cause actual and continuous damage to the health of the eyes and skin, and can induce degeneration of cells, fibrous tissue, and blood vessels. In mild cases, skin sunburn and corneal inflammation may occur. In severe cases, the immune system may be suppressed, and even skin damage may occur. cancer. According to the statistics and estimates of the World Health Organization, about 2 million to 15 million people are blinded by cataracts every year, and more than 20% of the blinded people may be caused by the ultraviolet radiation of sunlight. In addition, there is gro...
