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
The application requires a SensorTile.box board connected to the PC through USB. The board declares itself as a USB CDC class device.
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.
$ minicom -D <tty_device> -b 115200Replace <tty_device> with the port where the SensorTile.box board
can be found. For example, under Linux, /dev/ttyUSB0.
The -b option sets baud rate ignoring the value from config.
The sample code outputs sensors data on the SensorTile.box console.

If you move the board around or put your finger on the temperature sensor, you will see the accelerometer, gyro, and temperature values change.
