SMS‐CQ: A Quality and Safety Traceability System for Aquatic Products in Cold‐Chain Integrated WSN and QR Code

Abstract

AbstractAs one of the widely consumed foods, aquatic products are prone to spoilage and deteriorate in the cold chain. It is very important and necessary to trace and track the aquatic products' quality and safety in the cold chain. This paper aims to develop a quality and safety traceability system integrated with wireless sensor network (WSN) and quick response (QR) code (SMS‐CQ) for aquatic products. This paper analyzed temperature fluctuations of aquatic products in cold‐chain logistics that is implemented and evaluated in an actual cold chain. The results show that compared with the traditional system, SMS‐CQ is an effective quality management tool that leads to real‐time monitoring and tracing of the aquatic products in the cold chain: WSN technology enables SMS‐CQ to automatically realize the real‐time temperature acquisition, wireless remote transmission and monitoring; QR code provides valid means for the QR code generation, error correction and static and sensed dynamic information inquiry.Practical ApplicationsThe proposed method could be extended by future researchers or practitioners for future work in many wide areas in cold‐chain monitoring and traceability applications.
