Cold Chain Logistics Process Temperature Monitoring for Automated Data Access and Traceability
(by Gateway + Bluetooth Sensors)
These systems are designed to read data from all BlueTag series data loggers that pass by the gateway, with automated data access and traceability wirelessly. They are mainly composed of Bluetooth data loggers, a gateway, a router, cloud platform, and mobile APP, etc. When the BlueTag series data loggers shipped with the products come to the expected gateway and successfully communicate with the gateway via Bluetooth, the gateway will automatically collect the temperature and humidity data from the loggers and upload the data to the cloud using the WiFi router as a relay or directly via the 4G network, depending on the gateway model, WiFi Bluetooth Gateway or 4G Bluetooth Gateway. Finally, users can use the mobile APP or computer platform to check and trace the data remotely.
