In 1999, the concept of Internet was put forward. In the same year, the Chinese Academy of Sciences started the research of sensor networks and established some applicable sensor networks. The Internet of things is not a technological fantasy, but another technological revolution. In the past, the Internet of things was called sensor network in China.

The Internet of things is an information carrier such as Internet and traditional telecommunication network, which enables all ordinary objects that can exercise independent functions to realize interconnection. In recent years, China’s Internet of things industry has developed rapidly, and the scale of the industry has grown rapidly. With the continuous development of artificial intelligence, Internet of things and other industries, as an important part of the sensor market is also developing rapidly. It can be seen that as a standard configuration in the era of Internet of things, the sensor market has “unlimited scenery”.

Sensors become the standard configuration in the era of Internet of things

It is reported that sensors are the main way and means to obtain information in the field of nature and production. In modern industrial production, especially in the process of automatic production, various sensors should be used to monitor and control various parameters in the production process, so that the equipment can work in a normal or good state, and the product can achieve good quality.

Sensors are the source of data collection, they are everywhere. The sense of situation needed by the intelligent frontier basically starts with sensors. Whether it’s intelligent manufacturing, intelligent city, intelligent medical treatment, or intelligent devices and big data analysis, no matter how huge the intelligent system is, it must start from the cutting edge of sensors.

In addition, sensor, computer and communication are known as the three pillars of information system. The advantages and disadvantages of sensor technology have become an important symbol to measure a country’s scientific and technological level and whether it is at the commanding height of international strategic competition. It is the core basic technology that developed countries attach great importance to and compete for development.

When talking about the importance of sensors, industry experts pointed out that if a person is regarded as a complete information system, then the mutual information between face and skin and the outside world is “data information”, and the sensory organ is the data acquisition equipment, which is the core of data collection. In fact, the corresponding physical device is the sensor product, so the sensor is also called “electronic facial features”; 5g and other communication technologies are called human nervous system; computer is called human brain, which is responsible for and performs data processing functions.

In addition, the information industry may become one of the important driving forces of China’s economic growth in the future. At the same time, among the 22 technologies announced by the United States that are crucial to the country’s long-term security and economic prosperity, six are directly related to sensor technology. Therefore, the importance of sensors is obvious.

Finally, the sensor is a kind of detection device, which is usually composed of sensitive elements and conversion elements. It can measure information and also let users perceive information. It is called “electric facial features”. Sensors are widely used in metallurgy, petroleum, chemical industry, electric power, transportation, water conservancy, new energy, electronics, environmental protection, household appliances, aerospace, aviation and other fields of national economy, national defense, scientific research and other fields.
