Practical IoT MQTT Implementation

Is the Internet of Things hot? I think it is.

In fact, the Internet of Things has unconsciously integrated into our lives, bringing us convenience, such as smart locks, ETC electronic toll collection systems, etc. At first, everyone felt it was quite novel, but now it has become commonplace.

It can be said that the Internet of Things is an inevitable trend in the development of the Internet, especially now that 5G provides the necessary support. Moreover, many large companies in China have begun to布局物联网. For example, the well-known Xiaomi smart home; cloud computing companies and Internet giants like Alibaba Cloud and Tencent Cloud have also invested heavily in the IoT industry.

With business opportunities coming, there is naturally a greater demand for talent. It is not an exaggeration to say that IoT development is a blue ocean, with fewer people and more money. And it will become even hotter in the future.

How to learn and understand the Internet of Things?

Many people feel that the Internet of Things is difficult to master, which is because the knowledge involved in the Internet of Things is vast, including communication technology, embedded development, Internet systems, big data, artificial intelligence, etc., which can be said to be “intertwined”.

But I have seen a very good method that divides the Internet of Things into three levels from the overall architecture:

The first is the device layer, which consists of various hardware devices;

The second is the network layer, which mainly focuses on the communication protocols between devices and the IoT platform;

The third is the application layer, which is where specific business logic is implemented.

Summarized in a diagram, it is the one below👇.

This content comes from the Geek Time column “Practical IoT Development”, authored by Alibaba P8 Guo Zhaobin. I have already gone through it twice and joined the course group. I can say that this is the first time I have seen someone organize and explain such a vast amount of IoT knowledge clearly. Moreover, the course content has become IoT job interview questions.

In a nutshell, the course content is summarized as Guo Zhaobin combining his work experience in the Xiaomi ecosystem to organize the vast professional knowledge in the IoT field, analyze key IoT technologies, and guide everyone to implement a smart home project from scratch.

I have recommended this course before, priced at ¥129, and it has already been studied by 13,000 people. Recently, I found that Geek Time has launched a membership card. Friends who are familiar may know that I have recommended many courses from Geek Time: “Operating Systems”, “Network Protocols”, “Algorithms”, etc. The content is indeed good and very suitable for us, so seeing this monthly card for only 6 yuan, you can read over 200+ courses and 1400+ technical videos, I thought to recommend it to you.

Who is the author Guo Zhaobin?

He is currently a senior technical expert at Alibaba, former director of the IoT division at Xiaomi ecosystem company Miao Miao Ce, and has served as a senior engineer at Nokia and Microsoft.

He has over ten years of experience in the software and hardware field, having designed cold chain monitoring systems for the pharmaceutical and fresh food industries, accumulating rich theoretical and practical experience in IoT; he has extensive practical experience with one of the world’s largest consumer IoT platforms – Xiaomi IoT platform. It can be said that Guo Zhaobin is very clear about the entire knowledge system of the Internet of Things and has in-depth research on related technologies.

How is this column designed?

Combining a simple smart home project, it deeply analyzes the core knowledge points of the three major layers of the Internet of Things.

Basic Part: First, according to the path of device access to the network, dialogue with the platform, data transmission, and utilizing data to create value, I will introduce the basic framework of the IoT system, allowing you to initially understand the three major layers: device layer, network layer, and application layer; then through a simple IoT system in a smart home scenario, help you establish a more intuitive understanding.

Advanced Part: Combining a simple smart home project, it analyzes the core knowledge points of the three major layers of the Internet of Things and provides targeted supplements on open-source ecology, user privacy, and system security practices;

Practical Part: Customizes a practical project for you, explaining the implementation steps and precautions step by step around the simple IoT system of smart home.

Works completed by everyone in the course

Extra Content: Introduces the future development trends and key practice areas of the Internet of Things, such as the application of new communication technologies like 5G.

2022 Special Additions: You may have heard of the development background of RISC-V, here based on the Pingtouge RVB2601 development board, the previous “Practical Part” smart light and automatic watering experiments will be upgraded.

Considering the impact of RISC-V on the IoT industry, the teacher has specially planned this expanded content, hoping it will be of help to your actual work.

Having said so much, let’s take a look at the detailed content through the directory:
