IOT Weather Station

/* MAY 24th Sketch

  Sketch generated by the Arduino IoT Cloud Thing "May24th"

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  float humidity;

  float pressure;

  float temperature;

  Variables which are marked as READ/WRITE in the Cloud Thing

  will also have functions which are called when

  their values are changed from the Dashboard.

  These functions are generated with the Thing and added

  at the end of this sketch.
