 * @brief Air Quality 12 Click example
 *
 * # Description
 * This example demonstrates the use of Air Quality 12 Click board by reading the
 * IAQ 2nd Gen measurements and displays the results on the USB UART.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and configures the Click board to the default configuration.
 * Then it reads the sensor product ID, firmware version, and the 48-bit tracking number.
 *
 * ## Application Task
 * Checks the data ready interrupt pin and then reads the IAQ 2nd Gen measurements
 * and displays the results on the USB UART. The GP1 LED turns ON during the data reading.
 * The data sample rate is set to 3 seconds for the IAQ 2nd Gen operating mode, and the first
 * 100 samples upon startup should be ignored since the sensor is in the warm-up phase.
