 * \brief Weather Click example
 * 
 * # Description
 * This demo-app shows the temperature, pressure and humidity measurement using Weather click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring clicks and log objects.
 * Setting the click in the default configuration to start the measurement.
 * 
 * ## Application Task  
 * Reads Temperature data, Relative Huminidy data and Pressure data, 
 * this data logs to USBUART every 1500ms.
