Keywords: Sensor development trend

The sensor is a detecting device that can sense the measured information and can transform the detected information into an electrical signal or other required form of information output according to a certain law to meet the information transmission, processing, storage, Requirements for display, recording, and control. It is the first step in achieving automatic detection and automatic control. The general sensor consists of three parts: a sensitive component, a conversion component, and a measurement circuit.

"In the next five years, the average sales growth rate of the domestic sensor market will reach 31%." Luo Baihui, chief analyst of Jinmo Industrial Control Network, said that the main driving force for the rapid growth of local sensor demand is from industrial electronic equipment and automotive electronics, communication electronics, and consumption. Electronic and special electronic equipment, etc. Industrial electronics and automotive electronics are among the fastest growing industries in the electronic information industry, and are the areas where sensors are the most used, such as measuring various process variables, electronic and physical quantities, and traditional motion/positioning.

Although China's sensors have high market demand and rapid development, there are also problems such as low technical level, lack of types, and poor research and development capabilities. At present, there are 1,688 enterprises engaged in the research, production and application of sensors in China, but there are only more than 50 MEMS development and production, and the scale and application are small. The lack of sufficient scale application has led to the problem of low-tech but high-priced sensors in China, which have lost their advantages in the international market and made the market more competitive.

China's sensor industry is lagging behind, domestic sensor demand, especially high-end demand is heavily dependent on imports, and the localization gap is huge. At present, sensor imports account for 80%, and sensor chip imports account for 90%. The demand for localization is urgent. Luo Baihui pointed out: "At present, from the perspective of the entire gas sensor field, although the technology is stable, the threshold is very low. The future direction can only be high-precision." The development of the Internet of Things will greatly advance the development of the sensor field. There will be great applications in the fields of energy, intelligent sensing, security monitoring, and environmental protection. The development prospects and application fields of sensors are constantly expanding. Whether it is the automation industry or the construction of smart cities, including the development trend of the Internet of Things, it is showing people how brilliant the sensor industry will usher in.
