Troubleshooting
Ideal Installation Recommendations
For ideal measurements, Infineon has several recommendations for installing the sensor in the final application found in this application note. The list below outlines most of them but for complete information, refer to the app note linked above.
- Allow a space above the sensor at least 12mm tall with a minimum opening size of 14mm x 14mm.
- Avoid direct airflow in front of the sensor.
- Isolate the sensor from ambient heat sources.
- Isolate the sensor from vibration sources.
- Avoid placing the sensor in direct sunlight.
- Prevent any condensation/water contact with the sensor.
Calibration Procedure
The PASCO2V01 sensors require a week long calibration period, measuring every 10 seconds. During that period, the sensor must be outside for at least 30 minutes while taking measurements. Refer to the Automatic baseline offset correction (ABOC) and forced compensation scheme (FCS) application note for complete information about the calibration process. The graph below shows three sensors data outputs merge together during our calibration testing:
