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!
衝電氣(OKI)推出內建運算放大器的紫外線( UV )傳感器IC—— ML8511 。該產品運用絕緣上覆矽( SOI )-CMOS，為該公司首款模擬電壓輸出、無濾光器的UV傳感器。
OKI的UV傳感器IC由於採用了容易高整合度的SOI-CMOS技術，適合於數字及模擬電路。OKI表示，該公司未來將靈活運用這一特長，加強與連接微處理器的數字輸出電路，進而與感測式亮度控制傳感器(Ambient Light Sensor)構成單一芯片的商品陣容；未來的產品希望不僅能做到對一天的UV量一目了然、且隨時能掌握UV危險度的裝飾性量測設備，並且將應用推廣至家電設備、可攜式設備領域。
ML8511可與UV光量成正比輸出模擬電壓。由於可以輸出電壓，因此可以直接連接內建MCU的A/D數字/模擬轉換器，無需光電轉換電路。而且使用小型、薄型表面封裝方式，適合於便攜式設備用途。
