MicroPython-VEML6075

Driver base for the VEML6075 UV Light Sensor

The VEML6075 senses UVA and UVB light and incorporates photodiode, amplifiers, and analog/digital circuits into a single chip using a CMOS process. When the UV sensor is applied, it is able to detect UVA and UVB intensity to provide a measure of the signal strength as well as allowing for UVI measurement.
