6.3 Storage
When not in use, store the sensor in a dry, clean environment away from direct sunlight and extreme temperatures.
7. Troubleshooting
- No Data Output:
- Check power supply connections (VCC, GND) and ensure voltage is within 5-36V.
- Verify SPI interface wiring (RX, TX).
- Confirm host controller's baud rate matches the sensor's configured baud rate.
- Inaccurate Readings:
- Ensure the sensor is mounted securely and not subject to excessive vibration.
- Check for strong magnetic interference sources near the sensor.
- Verify the sensor's orientation matches the expected axis definitions.
- Intermittent Connection:
- Inspect cable for damage or loose connections.
- Ensure proper grounding of the sensor and host system.
