+/***************************************************
+  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
