 * @brief PIR 2 Click Example.
 *
 * # Description
 * This example demonstrates the use of PIR 2 Click boards.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and selects the driver interface.
 *
 * ## Application Task
 * It checks if the sensor has detected movement and displays message on the USB UART.
