equipment through the Internet.2, communication "refers to data communication only, that is, through the computer network system and communication system to achieve the end-to-end transmission." The communication "letter" refers to the information (information), the information carrier is the binary data, the data can be used to express the traditional media form of information, such as sound, image, animation and so on. "Communication" weighs on the
What is the MQTT protocolMQTT (Message Queuing Telemetry transport protocol) is a lightweight two-way message Transfer protocol developed by IBM in 1999 for applications such as the Internet of Things (IoT), primarily to address the problem of communication between devices used on the IoT and communication between these devices and back-end application systems.Why an MQTT (or similar) protocol is requiredWi

The most common architecture partitioning method for the Internet of Things is to divide the overall architecture into 3 levels, the perceptual layer, the network layer and the application layer.
The perceptual layer is at the bottom: it has two functions: collecting the environmental information through the sensor, and interacting with the environment with the operation actuator on the other.
