VL53L0X V2 Troubleshooting
Common issues and solutions to help you get your sensor working
Common Issues
Issue: VL53L0X not showing on I²C bus.
Solution: Check that XSHUT is tied high and that SDA/SCL are correctly connected. Scan for address with I²C scanner.
Issue: Sensor gives fluctuating values.
Solution: Try averaging measurements and avoid reflective or dark objects too close to the sensor.
Issue: Constant 2000 mm or 0 mm readings.
Solution: Ensure object is within range and directly in front of the sensor. Add a delay between readings.
Debugging Tips
Use the Serial Monitor to check for error messages and verify the sensor's output. Add debug prints in your code to track the sensor's state.
Use a multimeter to verify voltage levels and check for continuity in your connections. Ensure the power supply is stable and within the sensor's requirements.
