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!
Oki (OKI) launched the built-in amplifier of the ultraviolet (UV) sensor IC–ML8511. The products used on the insulation cover Silicon (SOI)-CMOS, the company’s first analog voltage output, filter the UV sensor.
OKI high UV sensor IC thanks to easy integration of SOI-CMOS technology, suitable for digital and analog circuits. OKI said, the company future will flexible using this a specialist, strengthening and connection microprocessor of digital output circuit, then and sense measuring type brightness control sensor (Ambient Light Sensor) constitute single chip of commodity lineup; future of products hope not only can do on day of UV volume at a glance, and and at any time can master UV dangerous degrees of decorative sex volume measuring equipment, and will application promotion to appliances equipment, and can carrying type equipment field.
ML8511 analog voltage is proportional to the amount of UV light output. Because of the output voltage, so you can directly connect the built-in a/d d/a converter of the MCU, no photoelectric conversion circuit. And the use of small and thin package, suitable for use in portable equipment.
