Abstract:

Abstract: Aimed at need of Real-time monitoring for the entire process of cold chain, wireless sensor network node with characteristics of wiring easy, low cost, low power consumption based on ZigBee technology was established. It can be effectively implemented online collection and real-time monitoring for environmental information in logistics. The node is proposedusing Zigbee W ireless micro—controller JN5139-Z01-M02R1 as its core ，which is produced by Jennic Company and SHT75 as its sensors,which is produced by SENSIRON.The result of practical application demonstrates that the system is feasible and reliable.
