The Internet of Things starts from applications and uses the Internet and wireless communication network resources to transmit business information. It is an extension of the Internet and mobile communication network applications, and a comprehensive embodiment of automation control, remote control, telemetry and information application technologies.

The wave of information revolution. The Internet of Things has received great attention all over the world. With the introduction of policies such as the "12th Five-Year Plan for the Development of the Internet of Things" and "Made in China 2025", it has been upgraded to a key direction of national technology and industrial innovation.
What is the Internet of Things?

Many people may not understand what the Internet of Things is. What are the key technologies of the Internet of Things? The Internet of Things is based on applications and uses the Internet and wireless communication network resources to transmit business information. It is an extension of the Internet and mobile communication network applications. It is a comprehensive embodiment of automation control, remote control, telemetry and information application technologies.

The Internet of Things is a complex and diverse system technology. From the perspective of the Internet of Things architecture, the Internet of Things can be divided into four levels: perception technology, transmission technology, support technology, and application technology.

Perception Technology

Perception technology refers to the technology used to perceive information at the bottom layer of the Internet of Things, including radio frequency identification (RFID) technology, sensor technology, GPS positioning technology, multimedia information collection technology and QR code technology.

Transmission technology

Transmission technology refers to the technology that can gather sensory data and realize data transmission in the Internet of Things. It includes mobile communication network, Internet, wireless network, WeChat communication, short-range wireless communication, etc. Short-range wireless communication mainly includes wireless LAN, Bluetooth, NFC (near field communication) technology and infrared transmission technology, ZigBee, and RFID.

Supporting technologies
are technologies used for IoT data processing and utilization, including cloud computing technology, embedded systems, artificial intelligence technology, database and data mining technology, etc.

Application technology
Application technology refers to the technology used to support the operation of IoT application systems. The application layer mainly develops and forms various industry application solutions based on the characteristics of the industry and uses Internet technology to build intelligent industry applications.

As the Internet of Things continues to develop and grow, smart homes are also becoming more intelligent. Therefore, smart sockets, smart TVs, smart air conditioners, smart refrigerators, smart lighting, etc. have changed our lives. In this process, wireless modules play a vital role - signal transmission.

The demand for wireless modules is growing as the market continues to grow, testing suppliers' development capabilities and batch supply capabilities. At the same time, in order to meet the needs of different categories of products, it is also necessary to provide simple and reliable system solutions.

The Internet of Things is a network based on information carriers such as the Internet and traditional telecommunications networks, which enables all common physical objects that can be independently addressed to be interconnected. It has three important characteristics: common object equipment, autonomous terminal interconnection, and ubiquitous service intelligence.

The key to the Internet of Things still lies in sensors + embedded technology.
