Core Components

Hardware Components

  • Industrial IoT Gateway Module 
    Acts as the central node, interfacing with field sensors (thermocouples, RTDs) via various protocols (RS-485, Modbus) and connecting upstream via Ethernet, WiFi, or cellular. 
  • Edge Processing Unit 
    Integrated into the gateway or deployed as a standalone unit, this component handles firmware-level analytics—filtering data, evaluating thresholds, and buffering in case of connection loss. 
  • Modular Sensor I/O Interface 
    Allows scalable deployment with plug-and-play connectivity, accommodating multiple sensor types without additional converters. 

Software & Systems

  • Gateway Management Software 
    Enables device configuration, remote firmware updates, diagnostics, and secure credential management—all accessible via a user-friendly web interface. 
  • Edge-to-Cloud Data Forwarding 
    Secure TLS-encrypted data push to GAO RFID cloud dashboards, where clients can view real-time temperature trends, set alerts, and export reports.
