    Study Notes

    IoT System Architecture

    • DAS (Data Aggregation and Conversion) performs data aggregation and conversion functions, such as collecting data, aggregating data, and converting analog data from sensors to digital data.
    • Advanced gateways connect sensor networks to the Internet, perform basic gateway functionalities like malware protection, filtering, and decision making based on inputted data and data management services.

    Sensing Layer

    • The sensing layer consists of sensors, actuators, and devices that accept data, process data, and emit data over a network.
    • Sensors or actuators in this layer accept physical or environmental parameters, process data, and emit data over a network.

    Physical Design of IoT

    • The physical design of an IoT system refers to the Things/Devices and protocols used to build an IoT system.
    • Node devices are used to build an IoT system, each having a unique identity that performs remote sensing, actuating, and monitoring work.
    • Protocols are used to establish communication between Node devices and servers over the Internet.

    IoT Devices

    • IoT devices are used to build a connection, process data, provide interfaces, provide storage, and provide graphics interfaces in an IoT system.
