The global sensor market is dominated by American, Japanese, and German manufacturers. Compared with foreign leading enterprises, China's sensor industry started late and has pain points such as weak autonomy in key core technology capabilities and high prices, which urgently need to be addressed. Therefore, China attaches great importance to independent innovation of sensors and the construction of industrial ecology.

　　At present, sensors are widely used in various fields of social development and human life, such as industrial automation, modern agriculture, Space technology technology, Military engineering, robotics, resource development, ocean exploration, environmental monitoring, security, medical diagnosis, transportation, household appliances, etc.

　　From the upstream and downstream of the sensor industry chain, the upstream mainly focuses on the supply of raw materials for sensor manufacturing. Generally speaking, the raw materials for sensor manufacturing include semiconductor materials, metal materials, ceramic materials, and organic chemical materials. Representative companies of semiconductor material suppliers in upstream industries include Jiangfeng Electronics, Shanghai Silicon Industry, Ashi Chuang, Youyan New Materials, North Huachuang, etc; Representative enterprises of metal material suppliers include Baosteel, Jiangxi Copper, Aluminum Corporation of China Limited, Zijin Mining, etc; Ceramic material suppliers represent enterprises such as Fenghua High Tech, Guoci Materials, Weina Technology, etc.

　　The middle reaches of the sensor industry chain mainly involve the manufacturing and packaging of various types of sensors. From the development of China's sensor manufacturing level, there is still a certain gap between China and the international level.

　　Sensors are one of the three pillars of modern information industry, alongside communication and computer technology. They have a wide variety of products and a wide range of applications. With the continuous development of intelligent, digital and other technologies and emerging applications, the value of sensors continues to highlight. Foreign institutions have pointed out that the sensor market size in 2020 is about 170 billion US dollars, and it is expected to reach 342.8 billion US dollars by 2028, indicating its industrial prospects.

　　According to the research report "2023 * Edition Special Research Report on Sensor Industry Planning" by China Research Puhua Industry Institute, the current development status of China's sensor industry is as follows:

　　1、 Gradually expanding overall scale

　　In recent years, the overall scale of the development of China's sensor industry has gradually expanded, and it has been significantly applied in the automotive industry, including sensor applications in automotive tires, sensors in airbags, sensors in chassis systems, sensors in engine operation management systems, sensor applications and demands in exhaust gas and air quality control systems, and sensor applications and demands in ABS Sensor applications and requirements in vehicle driving safety systems, sensor applications and requirements in automotive anti-theft systems, sensor applications and requirements in engine combustion control systems, sensor applications and requirements in automotive positioning systems, and sensor applications and requirements in other automotive systems.

　　2、 Main production base

　　With the support of the government, China has made significant progress in sensor technology and its industry. Especially under the guidance of the dual plus project, which aims to accelerate efforts and development, a production base for sensitive components and sensors in China has been established.

　　At present, there are three major sensor production bases in China, namely the Anhui base, which mainly focuses on establishing economies of scale for force and photosensitivity; Shaanxi Sensitive Technology Industry Group Company mainly aims to establish economies of scale for electric pressure sensing, thermal sensing, and automotive electronics; The main goal of the Heilongjiang base is to establish a scale economy for gas and humidity sensitivity.

　　With the industrial transformation, factors such as miniaturization, microelectronics, software development, market driven, and IoT driven have become the characteristics of the development of the sensor industry. Nowadays, it has become a consensus in the industry that enterprises focusing on a single sensor business are difficult to grow and strengthen. Therefore, connecting the upstream and downstream of the industrial chain and building a good industry ecosystem have become important paths for the industry to achieve high-quality development, and also the key for Shenzhen to rely on the first mover advantage in the manufacturing industry to promote the expansion and strength of the intelligent sensor industry.

　　Although the sensor industry has broad prospects, as a technology intensive industry, it not only requires high-intensity investment, but also faces problems such as long industrial chains and difficulty in industrialization. In order to avoid causing enterprises to invest in a bet style and engage in low-level and disorderly competition, the role played by leading enterprises in the construction of industrial ecology is gradually being valued.

　　Entering the 21st century, the sensor manufacturing industry has begun to develop from traditional to intelligent. Intelligent sensors are equipped with microprocessors, which have the ability to collect, process, and exchange information. They are the product of the combination of sensor integration and microprocessors. Due to the important role of intelligent sensors in industries such as the Internet of Things, China has elevated the development of the sensor manufacturing industry to new heights, leading to a research and development boom and highlighting its market position.

　　In recent years, benefiting from the rapid growth of markets such as automotive electronics, consumer electronics, medical electronics, optical communication, industrial control, and instrumentation, the development of the intelligent sensor industry has shown an explosive growth trend. With the application and promotion of the Internet of Things in the industrial field, the application of intelligent sensors is becoming increasingly widespread, which is of great significance for the development of the Internet of Things industry.

　　The rapid development of emerging industries such as the Internet of Things and mobile internet has brought enormous development opportunities to the intelligent sensor industry, and China's intelligent sensor industry has broad prospects.
