In this study, a real-time surveillance system using Internet of Things technology is proposed for vaccine coldchains. This system fully visualizes vaccine transport and storage. It comprises a 4G gateway module, lowpowerand low-cost wireless temperature and humidity collection module (WTHCM), cloud service softwareplatform, and phone app. The WTHCM is installed in freezers or truck-mounted cold chain cabinets to collectthe temperature and humidity information of the vaccine storage environment. It then transmits the collecteddata to a gateway module in the radiofrequency_physical layer (RF_PHY). The RF_PHY is an interface forcalling the bottom 2.4-GHz transceiver, which can realize a more flexible communication mode. The gatewaymodule can simultaneously receive data from multiple acquisition terminals, process the received datadepending on the protocol, and transmit the collated data to the cloud server platform via 4G or Wi-Fi. Thecloud server platform primarily provides data storage, chart views, short-message warnings, and otherfunctions. The phone app is designed to help users view and print temperature and humidity data concerningthe transportation and storage of vaccines anytime and anywhere. Thus, this system provides a new vaccinemanagement model for ensuring the safety and reliability of vaccines to a greater extent.
