The 6-Axis IMU Usage on Seeed Studio XIAO nRF52840 Sense

Seeed Studio XIAO nRF52840 Sense is equipped with a high-precision 6-Axis Inertial Measurement Unit (IMU) which includes a 3-axis accelerometer and a 3-axis gyroscope. There is also an embedded temperature sensor on this module. We believe that this module can greatly help in your TinyML projects. This wiki will introduce the basics of using this IMU on this board.

Note

  • Seeed Studio XIAO nRF52840 is not equipped with this IMU module.
  • The IMU function will perform better when we use the "Seeed nrf52 mbed-enabled Boards Library", so we highly recommon that.

View accelerometer, gyroscope and temperature data on serial monitor​

In this example, we are going to view the accelerometer, gyroscope and temperature data from the Seeed Studio XIAO nRF52840 Sense on the Arduino Serial Monitor.

pir

  • Step 2. Open Arduino IDE, navigate to Sketch > Include Library > Add .ZIP Library... and open the downloaded zip file.

pir

  • Step 3. Navigate to File > Examples > Accelerometer And Gyroscope LSM6DS3 > HighLevelExample to open the HighLevelExample

pir

  • Step 4. Upload the codes and open the Serial Monitor

Note: Once you upload the codes, it will not be executed automatically until you click Serial Monitor on the upper right corner of the Arduino window.

pir

Now you will see the accelerometer, gyroscope and temperature data displayed one after the other on the serial monitor as above!
