RAKwireless RAK12019

RAK12019 is an Ambient Light sensor (ALS) or Ultraviolet Light Sensor (UVS), which is part of the RAKwireless WisBlock sensor series. The measured ambient light intensity and ultraviolet index are interfaced via the I2C bus making it immune to electrical noises, unlike its analog output counterpart. This module utilizes the LTR-390UV-01 sensor from Lite-On.
