RFID based Mobile Cold Chain Management System for Warehousing

A cold chain is a temperature controlled supply chain. An unbroken cold chain is an uninterrupted series of storage and distribution activities which maintain a given temperature range. It is used to extend and ensure the shelf life of products such as fresh agricultural produce, frozen food, photographic film, chemicals and pharmaceutical drugs. The only reliable way of verifying the real integrity of the cold chain consists of monitoring the temperature of the products during their distribution. The temperature monitoring of the product is done in the stages of transportation and storage. This paper focuses on monitoring and adjusting the temperature in warehousing, it has been achieved by using the combination of RFID Readers and Thermochron iButtons. The thermochron iButton connected with the reader is initialized with low and high threshold values. When a temperature value exceeds the threshold it should be intimated to the administrator. The administrator at the remote location will control or adjust the temperature of the system or further action will be executed. The advantages of the system are reducing the manual work in the monitoring, controlling process and reduction of wastages.
