Smart Cold Chain

Smart Cold Chain is an IoT-based monitoring solution designed to help businesses monitor temperature, humidity, and energy consumption across cold storage and refrigeration systems in real time.

The solution connects sensors and energy meters to an IoT Gateway, which collects data from each location and transfers it to a centralized monitoring system. This enables businesses to monitor operating conditions, identify abnormalities, analyze energy consumption, and manage multiple locations more efficiently.

Key Functions

• Temperature & Humidity Monitoring — Monitor cold rooms, refrigerators, and freezers in real time.
• Energy Monitoring — Track electricity consumption from main electrical panels and refrigeration equipment.
• IoT Gateway — Collect data from sensors and meters at each location and transmit it to the central system.
• Centralized Monitoring — View data from multiple stores or locations through one centralized platform.
• Alert & Notification — Detect abnormal conditions and support faster response.
• Data & Reporting — Store historical data for analysis, performance monitoring, and reporting.

Solution Flow:
Sensors & Energy Meters → IoT Gateway → Central Monitoring → Analysis & Alerts → Reporting
