GYML8511 Analog Output Ultra-Violet Light Sensor Module
Photodiode sensitive to UV-A and UV-B
Embedded operational amplifier
Analog voltage output
Detection Wavelength Band: 280nm ~ 390nm
Low supply current (300mA ) and low standby current (0.1mA )
Small and thin surface mount package (4.0mm x 3.7mm x 0.73mm, 12-pin ceramic QFN)
The GYML8511 Sensor works by outputting 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.
The ML8511 is an UV sensor, which is suitable for acquiring UV intensity indoors or outdoors. The sensor IC applies SOI-CMOS technology so it is widely used in digital circuits and analog circuits. According to the principle that photocurrent can be converted into voltage, the sensor can detect the UV intensity so it is a good choice for using in an external circuit. ML8511 can output analog voltage that is proportional to UV intensity.
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 an 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 the microcontroller to read UV Light intensity.
