/*
For configuration library:
DHT12 dht12("Scale temperature","ID device for I2C");
On "Scale temperature" you can select the preset scale:
CELSIUS, FAHRENHEIT or KELVIN.
And on "ID device", you can put ID sensor, on DHT12
normally is 0x5c.
Examples:
  DHT12 dht12;
The preset scale is CELSIUS and ID is 0x5c.
  DHT12 dht12(KELVIN);
the preset scale is KELVIN and ID is 0x5c.
  DHT12 dht12(FAHRENHEIT,0x53);
The preset scale is FAHRENHEIT and ID is 0x53.
