/*
  LoRa_Simple_Client_DHT11 for Arduino:
  Support Devices:
  1/ LoRa Shield + Arduino + DHT11 Temperature Sensor
  2/ LoRa mini / LoRa mini dev + DHT11 Temperature Sensor

  Hardware Connection:
  1/ Connect DHT11 vcc to 3.3v
  2/ Connect DHT11 GND to LoRa mini dev GND
  3/ Connect DHT11 Data pin to LoRa mini dev A0 pin

  Software Requirement:
  1/ Install the Radiohead Library(http://www.airspayce.com/mikem/arduino/RadioHead/) to Arduino.

  Example sketch showing how to get temperature and humidity value and send to
  LoRa Gateway: Detail refer
  http://wiki.dragino.com/index.php?title=LoRa_Mini#Example_2:_Multi_LoRa_nodes_simple_connection_--_RadioHead_Lib

  It is designed to work with the other example LoRa_Simple_Gateway_DHT11
