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.
