 * @file main.c
 * @brief DHT22 Click Example.
 *
 * # Description
 * This is a example which demonstrates the use of DHT22 Click board by
 * measuring temperature and relative humidity.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the SDA data pin depending on the selected GPIO pin (SDA1/SDA2)
 * and log module.
 *
 * ## Application Task
 * Reads the temperature and humidity from the sensor and 
 * displays the values on the USB UART.
