/**
 * @brief	This is the device handler class for the tmp1075 temperature sensor.
 *
 * @details	The tmp1075 communicates via I2C. After the address byte and the
 * 			read and write bit, a pointer address must be sent to the device.
 * 			This pointer address is stored in the pointer register of the
 * 			tmp1075 and defines to which address following data bytes will
 * 			be written or from which address data will be read.
