通过J1031C3VDC.15S和STM32F446RE，基于NTC热敏电阻的温度读数控制外部设备

 * @file main.c
 * @brief Thermostat 5 Click Example.
 *
 * # Description
 * This library contains API for the Thermostat 5 Click driver 
 * for temperature measurement and relay control.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C or ADC module and log UART set the relay to an OFF state.
 *
 * ## Application Task
 * The demo application measures temperature in degrees Celsius.
 * If the temperature increases above 30 degrees Celsius, 
 * the relay will turn ON, otherwise it will turn OFF.
 * Results are being sent to the UART Terminal, where you can track their changes.
 *
 * @note
 * For temperature measurement, we used Semitec 103AT-2 NTC Thermistors. 
 * - Beta parameter:  3435 K	
 * - Resistance:      10 kOhms	
 * - Tolerance:	      1 %
