 * @brief Thermo K 3 Click example
 *
 * # Description
 * This example demonstrates the use of Thermo K 3 Click board by reading and displaying
 * the temperature measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the temperature measurement in Celsius and displays the results on the USB UART
 * approximately once per second. If there's no thermocouple type-K probe inserted an
 * appropriate message will be displayed instead.
