使用BH1900NUX和STM32F446RE保持对温度波动的掌控

 * \brief Thermo13 Click example
 * 
 * # Description
 * The application measures temperature
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver init, configures the module and
 * reads the temperature Limit LOW/HIGH values that are set.
 * 
 * ## Application Task  
 * Reads ambient temperature data and this data logs to USBUART every 1500ms.
