1. The concept of IoT
When you start your day, the alarm goes off, and the coffee maker starts brewing. The lights come on as you walk through the house. Some invisible computing device responds to your voice commands, reads your schedule and news, and turns on TV news when you're ready. Your car will drive you to work through the least congested routes, allowing you to find time on the road to read or prepare for a morning meeting. We've read and seen those things in science fiction for decades, but they're either possible or imminent. All these new technologies are forming the basis of the Internet of Things (IoT).

Currently, a broad definition is that IoT uses information collection equipment such as RFID readers, sensors, Infrared sensors, GPS, and laser scanners to connect any item to the Internet according to the protocol. IoT carries out communication and information exchanges to realize intelligent identification, positioning, tracking, monitoring, and management of networks and systems.

2. Components of IoT
As can be seen from the definition, IoT includes the following four parts: 1) Diversified sensing: Diversified sensing devices such as traditional temperature sensors, humidity sensors, pressure sensors, flow sensors, position sensors, and new smart sensors support the digitization of the physical world and calibrate personnel positions. 2) Electronic identity: Electronic tags, QR codes, and visual and sound recognition are used for the construction and use of information systems to support the identification and tracking of people and objects. 3) Multi-mode communication includes Bluetooth, wireless communication technology (such as Wi-Fi, etc.), near-field communication technology, etc. 4) Intelligent management: It can effectively monitor and manage the physical world and the information world and improve the intelligence of the IoT system through in-depth analysis and visualization of perceptual data. Obviously, according to the definition of IoT, computer, transmission, communication, detection, and control are organically combined.
3. IoT application
The visual feast of the Winter Olympics is inseparable from the power of technology. In such a short month, the Winter Olympics not only made us deeply appreciate the Olympic spirit and the beauty of the ice world but also made people enjoy the visual feast attributed to black technologies. The phenomenon behind the black technologies is the curve overtaking China's IoT industry. The entire process of the opening ceremony adopts digital performance and analog technology. The effects of less staff, ethereal and romantic were achieved through the comprehensive use of artificial intelligence, 5G, AR, naked-eye 3D, cloud, and other technological achievements. The Smart Olympic Village has a temperature sticker with similar size to the Band-Aid. Smart beds can achieve sleep monitoring and automatic adjustment. Sterilization robots ranged from the preparation of dishes to delivery to restaurants. The Olympic Village technologies are the collection of robotics, IoT, and cloud computing. In addition to the new viewing e-paper technology, badge lighting and accurate venue temperature control were achieved. Overall, IoT technology assisted in the success of the Beijing Winter Olympics.
4. Key components of IoT
4.1 IoT chips
The IoT chip has many classifications in the market, and the process threshold is low. A large number of companies engage in the IoT area, including Huawei HiSilicon in the field of cellular chips, Tsinghua Unigroup Exhibition News, Lexin Technology in the WiFi Field, Huada Smart in the security chip field, Top Technology in the fingerprint identification field, Yuangu in the RFID field, and Tailingwei, Torch core, Shanghai Broadcom integration in the Bluetooth field, etc. In the field of IoT modules, the companies such as Guanghetong, Mobile Communication, etc. have the advantages of low cost, industrial agglomeration, rapid product iteration, and quick income growth. These companies gradually expand their market-leading advantages to the global market.
4.2 IoT module
The IoT module provides a variety of communication protocols. The flexible selection of cloud modules with various specifications is dependent on hardware types. High-cost-effective independent research and development modules for various communication methods can allow plug and play. Assuming the price of a single module is 30 yuan, China's IoT equipment value will reach 15 billion yuan in 2023, and the corresponding module market will achieve the value of 450 billion yuan.
