GY-ML8511 sensor module
ML8511 module is an easy to use ultraviolet light sensor. The ML8511 Sensor works by outputing an analog signal in relation to the amount of detected UV light . 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). Simply connect the output of the module to an ADC channel of microcontroller to read UV Light intensity.
