 * @brief Water Detect 2 Click Example.
 *
 * # Description
 * This library contains API for Water Detect 2 Click driver.
 * Water Detect 2 Click is used for detecting water and other electroconductive liquids. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes driver and performs the default configuration.
 *
 * ## Application Task
 * Reads fluid presence status and determines if there is fluid presence or not.
