* 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
