Intelligent Sensor Technology - With the development of semiconductor integrated technologies, microprocessors and memories continue to evolve. Sensitive components and signal processing circuits may be integrated on the same chip, so smart sensors will become a reality. Intelligent sensor is a microprocessor with both information detection, information processing, information memory, logical thinking and judgment of the sensor. The following focuses on the application of smart sensors and development. Intelligent sensors generally have a very strong real-time capabilities, in particular, often require dynamic measurements in a few microseconds to complete the data acquisition, calculation, processing and output. A series of smart sensor functions are carried out under program support. Such as the number of functions, the basic performance, ease of use and reliable work, mostly to a certain extent, depends on the software design and its quality, there are five major categories of these software. Including scale conversion, digital zero, nonlinear compensation, temperature compensation, digital filtering technology. The research of intelligent sensors in our country mainly focuses on professional institutes and universities. Beginning in the mid-1980s and the late 1980s, China National University of Defense Technology, Beijing University of Aeronautics and Astronautics, Zhejiang University and other colleges and universities successively reported the research results. In the early 1990's, several domestic research institutes successfully developed practical smart sensors using hybrid integrated technologies, marking that the research of intelligent sensors in China has entered the international ranks.

Intelligent sensors have been widely used in aerospace, aviation, defense, science and technology and industrial and agricultural production and other fields. For example, it has broad application prospects in the field of robots. Smart sensors enable robots to have human-like features and brain functions, and can sense various phenomena and perform various actions. However, compared with other countries, the product variety and quality level of sensors and instrumentation components in our country still can not meet the needs of the domestic market. The overall level is still at the level of the early 90s of last century. Therefore, in the next eight years, the sensor industry will focus on industrial control, automotive, communications and environmental protection services, focusing on sensors, flexible components, optical components, and specialized circuits, and will develop original products with independent intellectual property rights Technology and products; based on MEMS technology, based on integrated, intelligent and networked technologies, to strengthen the manufacturing process and the development of new sensors and instrumentation components so that leading products reach and approach the advanced level of similar foreign products; Increase variety, improve quality and economic benefits as the main objective to accelerate industrialization, so that domestic varieties of sensors and instrumentation components share 70% "80%, upscale products up to 60%. Smart sensor technology is a booming modern sensor technology, it relates to a micro mechanical and micro electronic variety of disciplines, signal processing technology, computer technology, circuits and systems, neural networks, fuzzy control and sensing technology and the like, who is a comprehensive technology.

Therefore, smart sensor technology plays an extremely important role in promoting industrial development. Currently, the global sensor market is showing rapid growth among the ever-changing innovations. Experts pointed out that the sensor technology will be the main area in the existing basis to be extended and improved, countries will race to accelerate the development and industrialization of a new generation of sensors, the competition will become increasingly fierce. The development of new technologies will redefine the future of the sensor market such as the advent of new sensors such as wireless sensors, fiber optic sensors, smart sensors and metal oxide sensors and an increase in market share.
