How do you know if your particulate matter sensor is bad?

2025-10-27

Here are common signs that your particulate matter (PM) sensor may be faulty or malfunctioning:

  1. ‌Inconsistent Readings‌: The sensor shows erratic or fluctuating PM levels when air quality is stable.
  2. ‌Stuck at Zero or Max‌: The sensor consistently reads 0 µg/m³ or max value regardless of actual conditions.
  3. ‌False Alarms‌: Frequent warnings or alerts occur even when there’s no visible dust or pollution.
  4. ‌Calibration Issues‌: Readings don’t match trusted air quality monitors or reference devices.
  5. ‌Slow Response‌: The sensor takes unusually long to detect changes in PM levels.
  6. ‌Physical Damage‌: Corrosion, moisture ingress, or visible wear on the sensor’s components.
  7. ‌Communication Errors‌: If connected to a system, it may fail to transmit data or show error codes.
  8. ‌Environmental Mismatch‌: Readings contradict obvious conditions (e.g., high PM indoors when windows are closed).

‌Troubleshooting Steps‌:

  • Clean the sensor (if applicable) to rule out dust buildup.
  • Restart or recalibrate the device per manufacturer instructions.
  • Compare readings with another reliable sensor.
  • Check for firmware updates or replace the sensor if issues persist.

If you suspect a faulty sensor, consult the user manual or contact the manufacturer for further diagnostics.
