+#################
+
+Overview
+********
+This sample provides an example of how to read sensors data
+from the SensorTile.box board.
+
+This sample enables all sensors of SensorTile.box board, and then
+periodically reads and displays data on the console from the following
+sensors:
+
+- HTS221: ambient temperature and relative humidity
+- LPS22HH: ambient temperature and atmospheric pressure
+- LIS2DW12: 3-Axis acceleration
+- LSM6DSOX: 6-Axis acceleration and angular velocity
+- STTS751: temperature sensor
+
+Requirements
+************
+
+The application requires a SensorTile.box board connected to the PC
+through USB. The board declares itself as a USB CDC class device.
+
+References
+**********
+
+- :ref:`sensortile_box`
+
+Building and Running
+********************
+
+Build and flash the sample in the following way:
+
+.. zephyr-app-commands::
+    :zephyr-app: samples/boards/sensortile_box
+    :board: sensortile_box
+    :goals: build flash
+
+Please note that flashing the board requires a few preliminary steps described
+in :ref:`sensortile_box`.
+
+Then, power cycle the board by disconnecting and reconnecting the USB cable.
+Run your favorite terminal program to listen for output.
+
+.. code-block:: console
+
+   $ minicom -D <tty_device> -b 115200
+
+Replace :code:`<tty_device>` with the port where the SensorTile.box board
+can be found. For example, under Linux, :code:`/dev/ttyUSB0`.
+The ``-b`` option sets baud rate ignoring the value from config.
+
+Sample Output
+=============
+
+The sample code outputs sensors data on the SensorTile.box console.
+
+ .. code-block:: console
+
+    SensorTile.box dashboard
+
+    HTS221: Temperature: 26.4 C
+    HTS221: Relative Humidity: 60.5%
+    LPS22HH: Temperature: 28.4 C
+    LPS22HH: Pressure:99.694 kpa
+    LIS2DW12: Accel (m.s-2): x: 0.306, y: -0.459, z: 10.031
+    LSM6DSOX: Accel (m.s-2): x: -0.158, y: 0.158, z: 9.811
+    LSM6DSOX: GYro (dps): x: 0.003, y: 0.000, z: -0.005
+    STTS751: Temperature: 27.0 C
+    1:: lps22hh trig 206
+    1:: lis2dw12 trig 410
+    1:: lsm6dsox acc trig 836
+    1:: lsm6dsox gyr trig 836
+
+    <repeats endlessly every 2s>
+
+If you move the board around or put your finger on the temperature
+sensor, you will see the accelerometer, gyro, and temperature values change.
