使用LHDULTRAM012UB3和STM32L073RZ实现全面和实时的空气流动数据

 * @file main.c
 * @brief AirFlow Click example
 *
 * # Description
 * This example showcases ability for device to read differential 
 * pressure, atmospheric pressure and ambient temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialize host communication modules (UART, I2C/SPI). Read 
 * electric signature data from device and logs it to terminal.
 *
 * ## Application Task
 * Reads differential pressure in Pa, atmospheric pressure in mBar 
 * and ambient temperature in C every 500ms and logs read data.
