Introduction

The VEML6075 is SparkFun's latest UV sensing solution. The VEML6075 implements a simple photodiode to measure the levels of UVA (320-400 nm) and UVB (280-320 nm) radiation. We can read the intensity of this light in irradiance, and from there, calculate the UV Index. The Qwiic UV Sensor has two spectrum ranges of measurement, UVA (365 ±10nm), and UVB. (330 ±10nm)
