Importance Of Learning Sensor Knowledge

Human beings are in the information age. The three pillars of information technology are measurement and control technology, communication technology and computer technology. However, sensor technology is the basis of measurement and control technology. The view that "without sensor technology, there is no modern science and technology" has been accepted worldwide. The sensor technology is materials science, mechanics, electricity, magnetism, microelectronics, optics, acoustics, chemistry, biology, precision machinery, bionics, measurement technology, semiconductor technology, computer technology, information processing technology, and even system science, Comprehensive high-tech intensive cutting-edge technologies that intersect with many disciplines, such as artificial intelligence, white dynamics technology, etc. , Medicine, environmental protection, materials, disaster prediction and prevention, agriculture, forestry and fishery, food, tobacco and alcohol manufacturing, construction, automobiles, ships, robots, home appliances, public safety and other fields can be said to be omnipresent. The sensor is the first in the automatic detection and control system, which is the window for sensing, acquiring and detecting information. The information to be obtained in scientific research and production processes must be converted into electrical or optical signals that can be easily transmitted and processed through sensors. The more developed science and technology, the higher the degree of automation.
The greater the dependence.
The development of sensor technology has also promoted the development of industry, agriculture, word navigation, military, sanitation and other technologies. The 21st century is the era when mankind has entered the electronic era of information in an all-round way. However, with the expansion of the space of human exploration, the types of natural information that people also need to obtain are increasing, the speed of information transmission needs to be accelerated, and the information processing capacity needs to be enhanced. Corresponding information acquisition technology, namely sensor technology, must keep up with the needs of information development. Sensors are the "tentacles" for humans to detect information in nature, and they also provide conditions and basis for people to recognize and control corresponding objects.

The development of sensors in foreign countries has a history of nearly 200 years. However, in the past 20 years, because of the widespread attention and investment in development of countries around the world, sensors have developed rapidly. The United States, France, Germany, the Netherlands, Russia, Japan and other industries have achieved industrialization. In the past ten years, the annual growth rate of world sensor output and market demand has been above 10%. At present, there are about 20,000 types of sensors in the world, and there are more than 5,000 units engaged in sensor development and production. The sensor industry in China dates back to the early 1950s, but it was not until the “Seventh Five-Year Plan” began in 1986 that sensor technology was officially included in national key research projects. It has invested in mechanical sensitivity, force sensitivity, gas sensitivity, humidity sensitivity, and biosensitivity. Five major researches on the subject. At present, about 3,000 kinds of sensors can be produced in batches or small batches in China, including more than 1,000 kinds of main sensor products and 950 kinds of domestic components, which basically cover all fields of information collection. Domestic product development covers a variety of sensors such as light, heat, force, voltage, magnetic, gas, humidity, sound, radiation, ion, and bio-sensitivity, as well as transmitters, secondary meters, and many others. Type of products, comparable to foreign research and development fields. During the Eighth Five-Year Plan period, China listed sensor technology as one of the key national key projects and key new technologies for medium and long-term scientific and technological development. The prosperity of computer and communication technology provides a huge platform for the widespread application of sensor technology. The development of related disciplines (such as materials science, microelectronics, mathematics, computer, information processing technology) and intersecting industries (such as electronic equipment manufacturing) provides theoretical support and material foundation for the development of sensor technology. It is believed that in the near future, Sensor technology will definitely make great progress.
