Smart sensors are sensors with information processing functions. Smart sensors with microprocessor, with the ability to collect, process and exchange information, is the product of sensor integration and microprocessor combination. Among them, MEMS as the representative of only sensors is the trend of sensor development.

A, China's intelligent sensor main enterprise analysis

1、Bitron Technology

Ltd. was founded in 2005 in Zhongguancun, focusing on the research and development, production and sales of wireless sensor networks, products with low energy consumption, low cost, small size, high efficiency, high reliability and other characteristics of the technology is at the international leading level. Its main business includes the R&D, production and sales of industrial monitoring systems, detection and analysis systems and MEMS sensor chips. According to the 2021 annual report released by Bicentennial, the company achieved revenue of RMB 845 million in 2021, an increase of 9.72% year-on-year.

2、Minxin

Minxin's main business is the research, development, production and sales of MEMS sensors. Its main products include MEMS acoustic sensors, MEMS pressure sensors and MEMS inertial sensors, etc. In 2021, Minxin's revenue reached RMB 35.2 billion, an increase of 6.57% year-on-year. Among them, the operating revenue of integrated circuit business accounted for 99.75 percent, with revenue of 35.1 billion yuan.

3、Square photoelectricity

The business scope of Sifang Optoelectronics includes the development, production and sales of sensors, analysis and testing instruments, automation instruments and photoelectric integration products. 2021 Sifang Optoelectronics revenue was 5.47 billion yuan, of which the gas sensor business accounted for 84.58%, with revenue of 213 million yuan.

Second, China's intelligent sensor industry development prospects

1, the growing maturity of the Internet of Things technology, driving market demand

With the continued popularity of the Internet of Things technology, technology and intelligence has been combined with more and more traditional industries, bursting out of smart phones, virtual reality, video interaction, smart cars, smart homes, smart meters, robots, smart security, 5G applications, smart medical and a series of emerging industries. The sensor as an intelligent detection device, and the development of the Internet of things is the same direction.

2, industrial technology upgrade to promote the rapid growth of market space

With the national industrial structure adjustment, high-end manufacturing development and the promotion of intelligent manufacturing and industrial Internet of things, intelligent sensors in the industrial field of application of new technical development characteristics. On the one hand, general-purpose sensor products as long as the non-electricity signal converted to a reliable power signal output. Intelligent sensors have increasingly high functional requirements, many complex applications of sensors have been AI and the original need for PC processing operations are embedded in the sensor internal implementation. On the other hand, with the development of the equipment manufacturing industry, advanced manufacturing has become the mainstream of industrial production and the vane, the community's unprecedented demand for precision measurement. Precision measurement means high quality products, low material loss and intensive labor, is the foundation of the intelligent manufacturing industry to achieve the value of the guarantee.

3、Policy to promote the rapid development of the industry

With the rapid development and upgrading of China's manufacturing industry, has given rise to a huge market for intelligent sensor applications. However, due to the late start of domestic sensor manufacturers, manufacturers of small-scale, brand and technology is still with the world's advanced level, there is a gap, resulting in the application of high-end manufacturing intelligent sensor market mainly depends on the United States, Japan, Germany and other international manufacturers. In recent years, the relevant state departments issued a series of policies to continuously increase support for the development of sensors and intelligent sensor industry.
