How often should I replace a PM sensor?

2025-11-21

The replacement frequency of a PM sensor depends on factors like sensor type, environmental conditions, and usage intensity. Here are general guidelines based on research and practical deployments:

 

  1. 1‌.Low-cost sensors‌ (e.g., Plantower PMS7003, Sensirion, Honeywell) typically require replacement every ‌1-2 years‌ due to faster degradation from humidity, particulate buildup, and electronic drift‌1. In high-pollution or high-humidity environments, replacement may be needed more frequently (e.g., every 6-12 months)‌
  2. 2‌.Regulatory-grade sensors‌ often last ‌3-5 years‌ but require regular calibration and maintenance‌
  3. 3‌.Signs for earlier replacement‌ include:

    For optimal performance, monitor sensor health using drift-detection tools like CurrentSense and follow manufacturer-specific recommendations.

    • Drift in readings despite calibration

    • Physical damage or clogging

    • Inconsistent data output
