Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not detected | Wrong wiring or address | Check SDA/SCL connections and I2C address |
| No data output | Missing pull-up resistors | Add 4.7kΩ resistors on SDA/SCL |
| Incorrect readings | No warm-up time | Allow sensor to stabilize for a few minutes |
| Gas values not changing | Heater not enabled | Enable gas measurement in library |
| I2C communication error | Loose connection | Recheck wiring and solder joints |
| Extremely high temperature reading | Self-heating effect | Add software offset correction |
| Humidity stuck at value | Sensor saturation | Improve airflow around sensor |
| Device not powering on | No VCC supply | Verify 3.3V power input |
