Electrochemical sensors generally show temperature dependence and cross-sensitivity to other trace gasses. The bias of the readings is strongly affected by changes in relative humidity (for example going from indoors to outdoors). | Electrochemical sensors generally show temperature dependence and cross-sensitivity to other trace gasses.

Sensor readings tend to drift over time. Regular recalibration is essential. | Sensor readings tend to drift over time. Regular recalibration is essential. |
