Pros: Cost-effective, extensive documentation, active community, good accuracy
Cons: Sensitive to humidity, limited lifespan (fan aging), requires regular calibration
Q4: What applications is the PMS5003 suitable for?
✅ Indoor air quality monitoring / DIY air monitor / Educational research / Embedded air purifiers
❌ Long-term unprotected operation in high-humidity kitchens, bathrooms, and outdoors
Q5: What should I consider when purchasing and selecting a model?
Confirm the model number (PMS5003, not PMS503)
Confirm the origin (Plantower, made in China)
Request a datasheet and batch number
Ask about lead time and warranty
5. In-depth comparison (a bonus point)
PMS5003 vs. SDS011 (common comparison)
PMS5003 vs. PMS7003 (smaller size, similar performance)
Suggest tabular comparison to improve dwell time and SEO keyword coverage
6. Practical Experience/Tips
Startup warm-up time and data stability
Suggest adding a sliding average algorithm to avoid false positives
How to extend lifespan (keep dry, dust-proof filter)
7. Summary & Call to Action
