 * \brief Smoke Click example
 * 
 * # Description
 * This Click includes internal LEDs, photodetectors, optical elements, and low-noise electronics 
 * with ambient light rejection. The sensor can detect a wide variety of smoke particle sizes. 
 * It also has an on-chip temperature sensor for calibrating the temperature dependence of the 
 * particle sensing subsystem. The temperature sensor has an inherent resolution 0.0625°C.
 *
 * 
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes I2C driver, applies "set registers check green values" settings, 
 * "enable FIFO data ready interrupt" and makes an initial log.
 * 
 * ## Application Task  
 * This example demonstrates the use of Smoke Click board. It reads reflected green values and
 * temperature from an internal sensor and displays the results on USART terminal.
 * It usualy takes two or three readings in order to get corect readings. Expect big values when you do.
