A cold chain is an uninterrupted supply system which maintains the quality of products from production through to transportation, distribution, storage, and retail by using temperature-controlled environments.

An unbroken cold chain provides a safe, temperature-controlled environment for sensitive items such as fresh and frozen food products, pharmaceutical products, biologics, chemicals, and vaccines.

The cold chain is essential for maintaining the quality of these high and low-risk perishable products and ensuring they arrive in optimal condition, fit for use or consumption.

How does a cold chain use IoT?

A smart cold chain system uses IoT to enhance monitoring by enabling real-time logistic management of every link in the chain.

It does this by using sensor-based technology which allows sophisticated real-time data tracking. Instead of manually collecting data by examining data gauges, connected sensors continuously monitor the environmental conditions of every part of the system.

Sensors connect with a smart IoT ecosystem and are powered by secure global connectivity, allowing products to be tracked wherever they are in the cold chain at any given moment.
