使用STHS34PF80和PIC18LF25K42开发红外存在和运动检测解决方案

 * @file main.c
 * @brief IR Sense 4 Click example
 *
 * # Description
 * This example demonstrates the use of theIR Sense 4 Click board™, 
 * by showing parameters for detection of the presence and motion as well as ambient temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C or SPI module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The application checks for the human presence and motion detection 
 * and display output data, using embedded algorithms, and ambient temperature in degrees Celsius.
 * Results are being sent to the UART Terminal, where you can track their changes.
