通过 WSP2110 和 STM32G431RB 告别空气污染

/*!
 * \file 
 * \brief Pollution Click example
 * 
 * # Description
 * Pollution click carries the VOC gas sensor and has high sensitivity to organic gases 
 * such as methanal (also known as formaldehyde), benzene, alcohol, toluene, etc.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * This is an example which demonstrates the usage of Pollution Click board.
 * Pollution Click reads ADC value, load voltage from ADC value, and reads corrected 
 * resistance of the sensor where results are being sent to the UART terminal 
 * where you can track changes.
