Calibrate BNO055 Sensors

To ensure the data from the accelerometer, gyroscope, and magnetometer is accurate, follow these steps to calibrate the sensors.

Calibrate Magnetometer

To fully calibrate the magnetometer of the BNO055 sensor:

1. Hold the sensor parallel to the ground and move it in a figure 8 pattern.

   Note

   Ensure that the sensor is far away from any magnetic interference.

   

2. Use the readCalibrationStatus function to read the calibration status of the sensor.

3. Repeat this process until the calibration value of the magnetometer is full.

Calibrate Accelerometer

To fully calibrate the accelerometer of the BNO055 sensor:

1. Place the BNO055 sensor in these six stable positions for a few seconds each.

   

2. Use the readCalibrationStatus function to read the calibration status of the sensor.

3. Repeat this process until the calibration value of the accelerometer is full.

Calibrate Gyroscope

To fully calibrate the gyroscope of the BNO055 sensor:

1. Place the sensor in any stable position for a few seconds.

2. Use the readCalibrationStatus function to read the calibration status of the sensor.

3. Repeat this process until the calibration value of the gyroscope is full.
