The development trend of the sensor industry in various fields

According to the data, there are currently about 6000 kinds of sensor products in my country, while the number of sensor products in foreign countries has reached more than 20,000, which is far from meeting the needs of the domestic market. Imports of mid-to-high-end sensors account for 80%, and import of sensor chips accounts for 90%. There is a huge gap in localization. Among them, there is a serious shortage of high-tech products such as digitization, intelligence, and miniaturization. High-end products required by the country's major equipment mainly rely on imports. As for the sensors and intelligent instruments and meters required by national security and major projects, foreign countries often impose restrictions on our country.

In the fields of science and technology, industrial and agricultural production and daily life, sensors are playing an increasingly important role. The higher and higher requirements of the human society on sensors are the strong driving force for the development of sensor technology, and the rapid advancement of modern learning technology provides a strong backing. With the development of science and technology, sensors are constantly updated and developed. Sensors, computers, and the Internet are known as the three major industries of information technology. With the gradual penetration of information technology into traditional industries, the range of sensor applications has been greatly expanded, and its role has become increasingly important.

Take the Internet of Things as an example. In the three fields of perception layer, transmission layer and application layer, the transmission layer and application layer mainly use computer, communication and Internet technologies, and the technology path is relatively mature. The perception layer composed of sensor systems mainly collects information and data for the Internet of Things, which is the foundation of the Internet of Things. It can be said that the development speed of the sensor industry determines the development of the Internet of Things industry.

In many application fields, although the sensor is an indispensable key device, it can only exist depending on the large industrial system. In many fields, it often needs to be tailor-made. Many individual fields have a small market size. Therefore, enterprises Should not blindly pursue scale. With the rise of emerging industries such as the Internet of Things, the sensor industry has become an important field for countries around the world to compete in the development of high-tech. my country's sensor industry is growing rapidly, and the application model is becoming more mature. However, due to low industrial grades and poor technological innovation capabilities, the domestic sensor industry presents a market pattern of excess low-end and mid-to-high end monopolized by foreign countries. The lagging development of sensor technology has hindered the smooth advancement of domestic strategic emerging industries.
