UV Sensor ML8511 (GY-8511)
Product information:
The ML8511 sensor breakout is an easy-to-use ultraviolet light sensor. The MP8511 UV sensor outputs an analog signal proportional to the amount of UV light it detects. This can be useful for creating circuits that warn the user of sunburn or detect the UV index in relation to weather conditions.
This sensor detects light most effectively from 280-390 nm. This is categorized as part of the UVB spectrum (burning rays) and most of the UVA spectrum (tanning rays).
The ML8511 sensor is very easy to use. It outputs an analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microcontroller can perform an analog to voltage conversion, you can detect the level of UV.
