The role of sensors


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 accurate and reliable information, and sensors are the main ways and means to obtain information in the fields of nature and production.
In modern industrial production, especially in automated production processes, various sensors are used to monitor and control various parameters in the production process, so that the equipment works in normal or optimal conditions, and the products reach the best quality. Therefore, it can be said that without many excellent sensors, modern production has lost its foundation.
In basic subject research, 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 at the macro level, the world of particles as small as fm at the micro level, and the evolution of celestial bodies over hundreds of thousands of years in the vertical view. , An instant response as short as s. In addition, various extreme technology researches, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic field, ultra-weak magnetic field, etc., which play an important role in deepening material understanding, opening up new energy and new materials, have emerged. Obviously, it is impossible to obtain a large amount of information that cannot be directly obtained by human senses without a suitable sensor. The obstacles to many basic scientific researches are, first of all, the difficulty in obtaining object information. The emergence of some new mechanisms and high-sensitivity detection sensors often leads to breakthroughs in this field. The development of some sensors is often the pioneer of the development of some marginal subjects.
Sensors have already penetrated into such a wide range of fields as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, biological engineering, and even cultural relic protection. It is no exaggeration to say that from the vast space, to the vast ocean, to all kinds of 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 developing economy and promoting social progress is very obvious. Countries all over the world attach great importance to the development of this field. It is believed that in the near future, sensor technology will take a leap, reaching a new level commensurate with its important status.
