 * \brief Moisture Click example
 * 
 * # Description
 * The demo application displays relative moisture measurement using Moisture Click.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes Driver and sets moisture gain, offset data and clock divider
 * and performs calibration of the device. We advise you not to touch,
 * or expose sensor to moisture during the calibration.
 *
 * ## Application Task
 * The device measure moisture and displays data in percentage every 500ms.
