Main Function Of Sensor

In order to obtain information from the outside world, people must rely on sensory organs. However, relying solely on people's own sensory organs is far from enough in studying natural phenomena and laws and in production activities. To adapt to this situation, sensors are needed. Therefore, it can be said that sensors are an extension of human five senses, also known as electrical five senses.
With the advent of the new technological revolution, the world has entered the information age. In the process of using information, the first thing to solve is to obtain accurate and reliable information, and sensors are the main way and means to obtain information in the natural and production fields.
In modern industrial production, especially in the process of automated production, 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 achieve the best quality. Therefore, it can be said that without numerous excellent sensors, modern production will lose its foundation.
In basic discipline research, sensors have a more prominent position. The development of modern science and technology has entered many new fields: for example, in the macroscopic view, we need to observe the vast universe of thousands of light years, in the microscopic view, we need to observe the particle world as small as fm, in the vertical view, we need to observe the evolution of celestial bodies for hundreds of thousands of years, and in the shortest instantaneous reaction of s. In addition, there are also various extreme technology studies that play an important role in deepening the understanding of matter, exploring new energy and new materials, such as ultra-high temperature, ultra-low temperature, ultra-high pressure, ultra-high vacuum, ultra-strong magnetic field, ultra-weak magnetic field, etc. Obviously, it is impossible to obtain a large amount of information that cannot be directly obtained by human senses without suitable sensors. The obstacle of many basic scientific research lies first in the difficulty of obtaining object information, and the emergence of some new mechanisms and highly sensitive detection sensors often leads to breakthroughs in this field. The development of some sensors is often the pioneer of the development of some marginal disciplines.
Sensors have long penetrated into extremely broad fields such as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, bioengineering, and even cultural relics protection. It is no exaggeration to say that from the vast space to the vast ocean, and even various complex engineering systems, almost every modern project cannot do without various sensors.
It can be seen that the important role of sensor technology in developing the economy and promoting social progress is very obvious. Countries around the world attach great importance to the development of this field. I believe that in the near future, sensor technology will take a leap and reach a new level commensurate with its important status.
