Definition & Explanation
Reefer cargo tracking is the continuous real-time monitoring of location, temperature, and humidity for refrigerated container shipments in international transit. IoT sensors inside the container transmit readings via satellite or cellular networks to cloud platforms accessible by freight forwarders, shippers, and consignees alike. Any deviation from agreed temperature thresholds triggers an automated alert – essential for perishables, pharmaceuticals, and biological samples that can deteriorate within hours of a cooling failure. Unlike standard container tracking, reefer tracking captures not just position but the physical condition of the cargo. The recorded data serves as compliance documentation for food safety and drug regulatory authorities, and as evidence in the event of an insurance claim.
