Create your thermo hygrometer using SHT45 and PIC18F57Q43

 * @brief TempHum 23 Click example
 *
 * # Description
 * This example demonstrates the use of Temp & Hum 23 Click board by reading
 * the temperature and humidity data.
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver, performs the sensor software reset and then reads
 * and displays the sensor unique serial number.
 *
 * ## Application Task
 * Reads the temperature (degC) and the relative humidity (%RH) data and 
 * displays the results on the USB UART approximately once per second.
