INDUSTRY FIELD GUIDE
Refrigerated warehouse temperature-event data for AI evaluation
A temperature spike in a refrigerated facility can reflect a real excursion, a door opening, a probe issue or missing telemetry.
NAICS 493120 · Refrigerated Warehousing and Storage
A temperature spike in a refrigerated facility can reflect a real excursion, a door opening, a probe issue or missing telemetry. The useful dataset pairs the signal with an independently recorded cause and a human review rule. FDA’s sanitary transportation guidance illustrates the importance of temperature control for covered food transport activities. Applicability to a specific operation depends on its activities and rules. FDA sanitary transportation guidance
Label the evidence around the spike
Start with a training logger or a simulation. Pair the trace with a fictitious product lot, location zone, sensor calibration information, door events and a verified cause. Include one missing sample and one harmless transient. Ask the buyer whether it needs anomaly detection, investigation support or label consistency. Keep any decision about releasing food with the authorized quality team.
Hold out a different sensor or operating pattern. Report timestamps, units, sampling interval and how missing values were handled. Make the labels traceable to a reviewer rather than inferring cause from the signal alone.
Avoid a live production test
Do not disrupt a cold room or use actual customer routes, health-related shipments, product identifiers, facility plans or sensor credentials without approval. Start with a simulator and written owner permission. Request a buyer’s acceptance rule before collecting a wider set.
Send a short schema and event example. State whether the readings are simulated, staged or authorized historical records. Describe a dataset
Original Fiund exercise
A verified door event explains one transient but not another logger gap
A detached training-logger simulation uses an imaginary lot and practice zone. No food, health shipment, live cold room, product-release decision or actual operating test is involved.
| Record | Source | What it records |
|---|---|---|
| CTM1 | Sensor A trace | At one-minute intervals: 4, 4, 6, 4 practice degrees C. Original event log independently confirms the staged door-prop event at the 6 reading; reviewer labels that interval a simulated transient. |
| CTM2 | Sensor B trace | 4, missing, 4. No independent event or maintenance record explains the missing sample. Different sensor and zone alias from A. |
| CTM3 | Review scope | A calibration card belongs to A only. Fixture has no food acceptance threshold, actual product condition or release authorization. |
Question for the model
Which interval has an independently linked explanation, and how should B's missing value and any release conclusion be handled?
Show the reference answer and checks
CTM1 links A's six-degree transient to its independently logged staged event and reviewer label. CTM2's missing B sample remains missing with unknown cause; A's event and calibration card do not transfer across sensors and zones. CTM3 supplies no acceptance rule or product evidence, so the packet supports neither a food-safety finding nor release. Preserve units, sample intervals and source-specific explanations without filling the gap or inferring cause from curve shape alone.
- Assigning a cause from a spike pattern without independent evidence.
- Filling missing telemetry with zero or copying another sensor's calibration and event explanation.
Fields to preserve
- Sensor, zone and lot alias
- Defines the trace.
- Unit, sampling interval and missingness
- Preserves measurement state.
- Independent event and reviewer scope
- Limits causal and release claims.
Test another case
Use a different simulated sensor where a similar spike has no event log. Require the cause to remain unknown despite the familiar shape.
Use original simulations or separately authorized training records. Exclude live systems and credentials; quality staff retain all product decisions.
