sensor in the current rapid development of automation industry, and the wisdom of the urban construction, etc., industry market expanded rapidly, but it is not very good in domestic sensor industry to grasp the market. Without it, single species from the technology in domestic can only be completed about 6000 kinds of localization, industry technology needs to be improved.
Industry market institutions say: & other; Currently from the point of the whole gas sensor field, although technical stability, but the threshold is very low. The future direction can be advanced. Throughout the &; And the development of the Internet of things will greatly promote the development of sensors, the sources of energy, intellisense, security monitoring, environmental protection and other fields will have great application. Predicts 2020, the industry scale will achieve 60 billion yuan of above, the localization rate of 70% or more.
China's sensor market continued growth in recent years, more than 15% growth rate. In 2012 China's top four sensor application areas for industrial and automotive electronic products, communications electronics, consumer electronics, special equipment, including industrial and automotive electronic products market share of about 42%, the size of the market reached 16 billion yuan, the sensor the market breaks through 50 billion yuan.


2012 China sensor industry overall scale expands gradually, significant applications in the automotive industry including sensor application in automobile tires, airbag sensor applications of the sensor application, chassis system, engine sensor in the operation management system application, exhaust gas and air quality control system of the sensor and the sensor application demand, ABS and the sensor application demand, vehicle security system and the sensor application demand, car alarm system and the sensor application demand, engine combustion control system and requirements, car positioning system, automobile sensor application and demand system of other sensor applications and requirements.

In addition, China sensor also has a new application in other fields, such as industrial control field, in the field of environmental protection, in the facility agriculture, and other relevant sensors in the field of multimedia image application. Review sensor industry in China, though developing rapidly, but there are some unfavorable factors. Such as on the product technology industry foundation is weak, the chasm between science and technology and production, product technology level is low, the products lack, the enterprise product research and development ability weak. But on the other hand, countries continue to develop good sensor industry development strategy and policy, the rapid development of the whole machine system market, throughout the year of emerging technologies push also become the positive factors for the development of sensor network.

Now there are about 40 countries around the world engaged in the development and production of sensor, research and development, production has more than 5000 units, more than 20000 kinds of products. 1688 domestic enterprises engaged in development, production and application of sensor, which is engaged in production of MEMS research and has more than 50, but the scale and application fields are small.

Since there is no large-scale application, domestic sensor product widespread low level of technology and the price is high. In the international market, Germany, Japan, the United States, Russia and other old industrial countries dominate the sensor market of enterprise, many manufacturers realize the large-scale production, some enterprise's annual production capacity of tens or even hundreds of millions. China, by contrast, the application range of the sensor UK Watson Wchangeorganisation imported sensor narrower, more applications remain based applications in industrial measurement and control, etc. Depend on it, sensor market competition is very fierce in China.


Therefore, sensor industry in our country in the future or will follow the following three directions:

First, industrial control, automotive, communications, environmental protection as key services, with sensors, elastic components, optical components, dedicated circuit as the key object, development with independent intellectual property rights of original technology and products.

Second, to increase the variety, improve quality and economic benefit as the main target, accelerate the industrialization, the domestic sensor species share reached 70% ~ 70%, high grade product of more than 60%.

Third, based on the MEMS technology, based on integration, intelligence and network technology, strengthen the manufacturing process and the development of new sensors and instrumentation components, to leading products and close to the advanced level of similar foreign products
