Description The ML8511 breakout is an ultraviolet light sensor which is easy to use The MP8511 UV ultraviolet Sensor works by outputing an analog signal in relation to the amount of UV light thats tested This breakout can be very handy in creating devices that warn the user of sunburn or test the UV index as it relates to weather conditions The range of the most effective light tested by the sensor is 280 390nm This is categorized as part of the UVB burning rays spectrum and most of the UVA tanning rays spectrum It outputs an 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 test 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 Package included 1 x GY 8511 ML8511 UVB rays sensor
