GY-ML 8511 UV Sensor

 

This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and part of the UVA (tanning rays) spectrum. It outputs an analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microprocessor can do an analog to voltage conversion you can detect the UV level. In power down mode, typical standby current is 0.1A thus providing a longer battery life.
