产品信息

The UVIS25 is a digital UV index sensor able to provide an accurate measurement of the ultraviolet radiation index (UVI) from sunlight. It includes a sensing element and a mixed signal ASIC to provide the UV index data through I2C and SPI interfaces.

A dedicated technology has been developed to achieve the greatest accuracy for UV index measurements.

The UVIS25 allows the measurement of the UV index, without the need for a dedicated algorithm to calculate the UV Index and without specific calibrations at the customer manufacturing line.

The device can be configured to generate interrupt events based on a threshold crossing or when a new set of data is generated. The event is available in a register as well as on a dedicated pin.

The UVIS25 is available in a full-mold LGA package (LGA). It is guaranteed to operate over a temperature range extending from -20 °C to +85 °C. The package is transparent to allow external solar radiation to reach the sensing element.

uvis25这是一个能够提供紫外线指数准确的数字测量紫外线指数(UVI)从阳光传感器。它包括一个传感元件和混合信号ASIC提供紫外线指数数据通过I2C和SPI接口。

已经开发了一个专门的技术,以达到最大的精度为紫外指数测量。

uvis25这允许紫外线指数测量,没有一个专门的算法来计算紫外线指数的需要,没有特定的校准客户生产线。

该设备可以被配置为基于阈值交叉或当一组新的数据产生时产生中断事件。该事件可在一个寄存器,以及在一个专门的脚。

在一个完整的uvis25模具LGA封装是可用的(LGA)。它是保证工作在温度范围从- 20°C延伸至85°C的封装是透明的,以允许外部的太阳辐射到达传感元件。
