/*
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*
* REVISION HISTORY
* Version 1.0 - epierre
* Contribution: bulldoglowell, gizmocuz
*
* DESCRIPTION
* Arduino UVM-30A
* Index table taken from: http://www.elecrow.com/sensors-c-111/environment-c-111_112/uv-sensor-moduleuvm30a-p-716.html
* Because this table is pretty lineair, we can calculate a UVI with one decimal
*
* Connect sensor:
*
* + >>> 5V
* - >>> GND
* out >>> A0
