         The default mode is ``NDOF_MODE``.
+
+        | You can set the mode using the line below:
+        | ``sensor.mode = adafruit_bno055.ACCONLY_MODE``
+        | replacing ``ACCONLY_MODE`` with the mode you want to use
+
+        .. data:: CONFIG_MODE
+
+           This mode is used to configure BNO, wherein all output data is reset to zero and sensor
+           fusion is halted.
+
+        .. data:: ACCONLY_MODE
+
+           In this mode, the BNO055 behaves like a stand-alone acceleration sensor. In this mode the
+           other sensors (magnetometer, gyro) are suspended to lower the power consumption.
+
+        .. data:: MAGONLY_MODE
+
+           In MAGONLY mode, the BNO055 behaves like a stand-alone magnetometer, with acceleration
+           sensor and gyroscope being suspended.
+
+        .. data:: GYRONLY_MODE
+
+           In GYROONLY mode, the BNO055 behaves like a stand-alone gyroscope, with acceleration
+           sensor and magnetometer being suspended.
+
+        .. data:: ACCMAG_MODE
+
+           Both accelerometer and magnetometer are switched on, the user can read the data from
+           these two sensors.
+
+        .. data:: ACCGYRO_MODE
+
+           Both accelerometer and gyroscope are switched on; the user can read the data from these
+           two sensors.
+
+        .. data:: MAGGYRO_MODE
+
+           Both magnetometer and gyroscope are switched on, the user can read the data from these
+           two sensors.
+
+        .. data:: AMG_MODE
+
+           All three sensors accelerometer, magnetometer and gyroscope are switched on.
+
+        .. data:: IMUPLUS_MODE
+
+           In the IMU mode the relative orientation of the BNO055 in space is calculated from the
+           accelerometer and gyroscope data. The calculation is fast (i.e. high output data rate).
+
+        .. data:: COMPASS_MODE
+
+           The COMPASS mode is intended to measure the magnetic earth field and calculate the
+           geographic direction.
+
+        .. data:: M4G_MODE
+
+           The M4G mode is similar to the IMU mode, but instead of using the gyroscope signal to
+           detect rotation, the changing orientation of the magnetometer in the magnetic field is
+           used.
+
+        .. data:: NDOF_FMC_OFF_MODE
+
+           This fusion mode is same as NDOF mode, but with the Fast Magnetometer Calibration turned
+           ‘OFF’.
+
+        .. data:: NDOF_MODE
+
+           This is a fusion mode with 9 degrees of freedom where the fused absolute orientation data
+           is calculated from accelerometer, gyroscope and the magnetometer.
