/**
* @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.
