Cold Storage Monitoring Across Multiple Sites

Problem Statement

A cold storage operator running multiple warehouse locations had no reliable way to monitor temperature and humidity across chambers. Manual logbook entries missed short excursions that could silently compromise stored goods. Energy usage across cooling units was completely untracked. And when it came to regulatory audits, the manual system couldn't produce the documented temperature logs that cold chain compliance required.

Our Solution

We built an IoT monitoring system with wireless temperature and humidity sensors deployed across all storage chambers and zones. Data is transmitted via WiFi, with 4G LTE as automatic backup, ensuring no gaps in monitoring even during network issues. CT clamp energy sub-meters on cooling units track power consumption in real time. A cloud platform brings all locations into a single dashboard with per-chamber temperature charts, configurable excursion alerts via email and SMS, energy trend analytics, and automated PDF compliance reports scheduled for regulatory audit submission.

Insights & Outcomes

Centralized visibility across all warehouse locations replaced fragmented manual logs with a single real-time dashboard. Automated excursion alerts catch temperature breaches before stored goods are affected, while 4G LTE failover ensures no data gaps even when WiFi goes down. Energy sub-metering made cooling unit consumption visible for the first time, enabling cost optimization. Automated PDF compliance reports replaced manual logbook preparation entirely making regulatory audits straightforward and fully documented.
