/***************************************************
  This is a library for the VEML6070 UV-A Sensor

  Works with the VEML6070 sensor from Adafruit
  ----> https://www.adafruit.com/products/2899
  Or knock-off sensors from aliexpress

  These sensors use I2C to communicate, 2 pins are required to
  interface
