Detection
A drift signature is the gradual change pattern in a sensor's behaviour that signals equipment degradation or calibration loss before outright failure.
Sensors don't always fail cleanly. More commonly, they drift: a slow, sustained deviation from the expected reading. The pattern of that drift — its slope, its periodicity, its relationship to other signals — is the drift signature.
Drift signatures are diagnostic. A temperature probe that drifts uniformly is probably losing calibration. A probe that drifts proportionally with humidity is probably suffering from condensation. A probe that drifts only during occupied hours is probably mis-mounted in airflow.
FrostLogic Explore catalogues drift signatures and matches new observations against them, producing not just "this is drifting" but "this is drifting in a way that matches calibration loss".
