Real-Time Cold Chain Temperature Monitoring System (RTMS)
An IoT-powered cold chain monitoring platform that replaces manual temperature logging with real-time deviation detection, automated alerts, and audit-ready compliance records across the entire cold chain.
Cold chain integrity relying on manual checks
A nationwide FMCG network operating cold rooms, reefers, and refrigerated transport struggled to maintain temperature compliance consistently. Without real-time monitoring, the entire cold chain depended on manual thermometer readings — creating dangerous blind spots between checks.
Temperature excursions went undetected until the next manual check, risking product quality, triggering compliance breaches, and exposing the business to regulatory and reputational risk.
Key Challenges
Manual thermometer readings causing delayed excursion detection
No centralised view of temperature deviations across sites and vehicles
Product quality risk during storage and refrigerated transport
Compliance breaches impacting audits and regulatory credibility
High dependency on manual logging and field verification
No historical temperature data for trend analysis or investigations
Key Requirements
IoT sensor integration across cold rooms, reefers, and vehicles
Real-time temperature visualisation and alerting
Automated deviation detection with escalation workflows
Centralised compliance database with full audit trail
Heat maps and trend analysis dashboards for leadership
Scalable architecture for future sensor types (humidity, vibration)
RTMS — IoT-powered cold chain intelligence
We built RTMS — an integrated monitoring platform using IoT sensors, encrypted data pipelines, and real-time visualisation dashboards to ensure temperature compliance across the full cold chain — from production storage to the final delivery vehicle.
IoT Sensor Network
Temperature sensors across cold rooms, production storage, reefers, and refrigerated vehicles
Real-Time Alerts
Automated deviation detection triggers instant alerts before product quality is impacted
Heat Maps & Dashboards
Regional performance heat maps and compliance dashboards for leadership visibility
Trend Analysis
Historical data surfaces patterns and supports proactive interventions
Encrypted Data Pipeline
Secure IoT data ingestion, validation, and processing end-to-end
Audit-Ready Records
Full temperature logs, threshold breaches, and alert history for compliance reporting
From reactive manual checks to proactive automated compliance
RTMS eliminated visibility gaps across the cold chain. Deviation detection that previously took hours — or was missed entirely — now triggers within seconds, allowing corrective action before product quality is impacted.
Leadership gained heat maps, regional performance dashboards, and trend analysis — enabling preventive interventions, reducing spoilage, and strengthening regulatory compliance confidence. RTMS established a scalable foundation for future expansion into humidity, vibration, and asset health monitoring.
