Why calibrate air quality sensors?

1. Key reasons to calibrate

Improves measurement accuracy.
Enables decisions based on real data.
Ensures compliance with environmental regulations.
Facilitates comparison between different devices.

2. Sensor types and calibration needs

All air quality sensors need calibrating, but not all behave the same.
Calibration needs vary according to their technology, sensitivity, and the environment where they are used.

These are the most common:

🧠 Did you know a sensor can keep working, but without calibration its data loses all technical and regulatory value?

3. Common calibration methods

  1. Laboratory: exposure to standard gas mixtures under controlled conditions.
  2. Co-location: comparison with official reference stations.
  3. Auto-calibration: algorithms like ABC that automatically adjust the baseline.

4. Consequences of not calibrating

🎯 An uncalibrated sensor may seem correct, but it will only be approximating… or getting it wrong.
