The problem
Multi-location operators need to know when refrigeration equipment drifts out of range before the paper logbook does, and they need records that hold up to food-safety review.
CONNECTED REFRIGERATION OPERATIONS
Frost Tracker
Know when cold storage needs attention, before the logbook catches up.
Frost Tracker connects refrigeration sensors, operational alerts, manual checks, corrective actions, and audit-ready records across locations.

CASE STUDY
From the workflow
to the working system.
Our approach
We modeled the operation as an organization → site → area → unit hierarchy, so every reading belongs to a piece of equipment and every rule knows where it applies.
What we built
LoRaWAN sensors connected through The Things Network, configurable thresholds with alert confirmation, quiet hours, SMS and email escalation, offline-first manual logs, corrective actions, calibration records, and exportable reports that support HACCP documentation.
What it shows
We can connect hardware, rules, and people into one accountable workflow.
THE CONNECTED WORKFLOW
Every event has a next step.

- 03Corrective action
- 04Audit record
Built for the details
of the operation.
Food-safety teams, facilities operators, and multi-location businesses responsible for refrigeration equipment and consistent operational records.
See the equipment behind the reading.
Temperature, humidity, door state, battery, and connectivity data live within an organization → site → area → unit hierarchy.
Respond to the right conditions.
Configurable thresholds, alert confirmation, quiet hours, and SMS and email escalation support deliberate responses to operational events.
Keep checks moving in the field.
Offline-first manual temperature logging complements connected sensors. Corrective actions record the response when an issue needs attention.
Keep an accountable history.
Calibration records, audit history, and exportable reports support HACCP documentation and food-safety workflows.
CONNECTIONS & CONTEXT
Connected to the work around it.
LoRaWAN sensors send readings through The Things Network. Configurable rules route confirmed events into SMS and email escalation. Sensor health remains visible alongside operational status.
Supports HACCP documentation and food-safety workflows. The software does not certify or guarantee compliance.
