- Drift: Gas-lab

In the context of gas sensing and electronic noses, refers to the gradual, unpredictable shift in sensor responses over time, often caused by sensor aging, contamination, or environmental changes.

: A signal processing technique that removes components of the sensor response that are not correlated with the target gas, effectively filtering out "drift noise". Gas-Lab - Drift

: A dynamic method that identifies samples away from the standard classification plane to better represent drift variations in real-time. In the context of gas sensing and electronic

A critical "helpful feature" or strategy for managing this issue is , which uses software-based signal processing to maintain accuracy without constant manual recalibration. Key Helpful Features & Methods A critical "helpful feature" or strategy for managing

: Modern systems extract both steady-state and transient features from the sensor's response. The relationship between these two can be used to adjust drifted readings back to a "month 1" baseline.
