As the "made in China 2025", "4.0" industrial "Internet of things" is put forward, such as the manufacturing industry in China is facing a challenge, especially for analytical instruments and sensor products develop in the direction of intelligence, informationization, network put forward higher requirements, in order to realize more sensitive, more accurate, faster, more reliable real-time detection. And sensor industry of our country industry present situation, market and future development prospects of how? Industry status quo China sensor market continued growth in recent years, more than 20% growth rate, the four major fields of sensor applications for industrial and automotive electronic products, communications electronics, consumer electronics products. 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-depth analysis of the domestic current situation of the sensor market 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.
