04.紫外线检测,UV light detection
code:104
Description:
The ML8511 breakout is an easy to use ultraviolet light sensor. The MP8511 UV (ultraviolet) Sensor works by outputing an analog signal in relation to the amount of UV light that’s detected. This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions.
This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microcontroller can do an analog to digital signal conversion then you can detect the level of UV!
冲电气(OKI)推出内建运算放大器的紫外线(UV)传感器IC——ML8511。该产品运用绝缘上覆硅(SOI)-CMOS，为该公司首款模拟电压输出、无滤光器的UV传感器。
OKI的UV传感器IC由于采用了容易高整合度的SOI-CMOS技术，适合于数字及模拟电路。OKI表示，该公司未来将灵活运用这一特长，加强与连接微处理器的数字输出电路，进而与感测式亮度控制传感器(Ambient Light Sensor)构成单一芯片的商品阵容；未来的产品希望不仅能做到对一天的UV量一目了然、且随时能掌握UV危险度的装饰性量测设备，并且将应用推广至家电设备、可携式设备领域。
ML8511可与UV光量成正比输出模拟电压。由于可以输出电压，因此可以直接连接内建MCU的A/D数字/模拟转换器，无需光电转换电路。而且使用小型、薄型表面封装方式，适合于便携式设备用途。
