Anonymised case study · Logistics / cold chain · Multi-site
Live cold chain temperature monitoring
Replacing paper temperature logs with sensor alerts across three sites — so excursions are caught in minutes, not at the end of a shift.
Challenge
Manual clipboard checks missed overnight spikes. Auditors wanted clearer records. Existing Wi‑Fi was consumer-grade and dropped in cold rooms. The operator needed alerts to phones without building a full SCADA project.
Approach
- Site survey: coverage, power, mounting and network separation
- Business Wi‑Fi remediation for cold-room reach (see network)
- Sensor install with threshold alerts to ops leads
- Simple dashboard + exportable logs for audits
- Runbook for battery/sensor replacement and false-alarm tuning
Results (anonymised)
- < 10 minutes median alert-to-acknowledge for critical excursions (vs end-of-shift discovery)
- 3 sites live within six weeks of kickoff
- Paper logbooks retired for the monitored zones
- Fewer “was the fridge ok overnight?” disputes with customers
Metrics are operational estimates from the engagement with identifying details removed. Individual results vary.
