使用 3SP-O3-20 和 PIC18F47K42 获得实时数据以监测和管理臭氧水平

 * @file main.c
 * @brief Ozone3 Click example
 *
 * # Description
 * This library contains API for the Ozone 3 click driver.
 * This demo application shows an example of the O3 ppm data measurement.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization the app set default settings.
 *
 * ## Application Task
 * This is an example that shows the use of a Ozone 3 click board™.
 * Get and logs O3 ( Trioxygen ) data as ppm value.
 * Results are being sent to the Usart Terminal where you can track their changes.
