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.
ML8511 UV light can be used with an analog voltage output proportional to the amount. Since the output voltage can therefore be directly connected to the MCU built A / D digital / analog converter, no photoelectric converting circuit. And the use of small, low-profile surface-mount package, suitable for use in portable devices.
