SHEET 01 · Case story

Find the record by cabinet and date in one place.

The food cold-storage warehouse brings temperature/humidity, events and reports together. Quality and facilities staff can look up historical records by cold-storage area and equipment to trace environmental conditions.

SHEET 02 · Challenge and response

From the site problem to a system approach.

  1. 01The challenge

    Chilled-food sites need environmental trends and alert records, but information can be scattered and difficult to trace.

  2. 02The system approach

    Create cold-chain and environmental dashboard views that bring temperature/humidity, events and reports together.

  3. 03Reported outcome

    Let quality and facilities teams use the same records to track environmental conditions.

SHEET 03 · Architecture

System architecture and data flow.

Site-sensor data enters the existing platform, which presents views by cold-storage area, equipment and alert threshold. Source diagrams retain some original Traditional Chinese labels.

SHEET 04 · Wiring and hardware

Wiring diagrams and hardware configuration.

The diagram outlines data flow between site signals, edge devices, the network and the platform. Confirm installation and connection scope before work begins.
