In order to obtain information from the outside world, people must resort to sensory organs. However, people's sense organs alone are far from sufficient in studying natural phenomena and laws as well as the flow of production. To adapt to this situation, sensors are needed. Therefore, it can be said that the sensor is an extension of the human five sense organs, also known as the electrical five sense features.
With the advent of the new technological revolution, the world has begun to enter the information age. In the process of using information, the first thing to be solved is to obtain correct and reliable information, and sensors are the main way and means to obtain information in the fields of nature and production.
In modern industrial production, especially in the automated production process, various sensors are used to monitor and control various parameters in the production process, so that the equipment works in a normal or better state, and the product reaches a better quality. Therefore, it can be said that without many excellent sensors, modern production will lose its foundation.
In the research of basic disciplines, sensors have a more prominent position. The development of modern science and technology has entered many new fields: for example, it is necessary to observe the vast universe of thousands of light-years on the macro level, the world of particles as small as cm in the microscopic view, and the evolution of celestial bodies for hundreds of thousands of years in the vertical direction. , An instant response as short as s. In addition, various extreme technology researches that play an important role in deepening the familiarity of substances, opening up new energy, new materials, etc., such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic field, ultra-weak magnetic field, etc. Wait. Obviously, it is impossible to obtain a large amount of information that cannot be directly obtained by the human senses without a suitable sensor. The obstacles to many basic scientific researches, first of all, are the difficulties in obtaining object information, and the emergence of some new mechanisms and highly agile detection sensors often leads to breakthroughs in this field. The development of some sensors is often the forerunner of the development of edge disciplines.
Sensors have already penetrated into such a wide range of fields as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, bioengineering, and even cultural relic protection. It is no exaggeration to say that, from the vast space, to the vast ocean, to various complex engineering systems, almost every modern project is inseparable from a variety of sensors.
It can be seen that the important role of sensor technology in economic development and social improvement is very significant. Countries all over the world are facing the development in this field very seriously. It is believed that in the near future, sensor technology will emerge as a Pentium, reaching a new level equivalent to its important position.
