Automated cold-storage temperature monitoring: HACCP compliance without paper logs

How to replace paper temperature logs with an automated sensor system, with alerts and Excel reports for HACCP and GSP audits.

AIoT Viet engineering team 26/09/2026Updated 27/09/2026

Many cold stores still have staff record temperatures by hand 2–3 times a day. It's error-prone, misses night-time incidents and is hard to prove during audits.

What can an automated system do?

Measure temperature every 1–10 minutes and keep a full history
Alert via Zalo/Telegram when out of range or a door stays open
Export daily and per-shift reports for HACCP audits

Where to start?

Begin with the 2–4 most critical measuring points. The Cold Storage Monitoring Pro Kit has all the devices and the app to run a pilot in one afternoon.

Where should you place temperature sensors in a cold room? A complete guide to temperature mapping
