Sensing technology, together with computer technology and communication, is called the three pillars of information technology.
From the perspective of the Internet of Things, sensor technology is an important indicator to measure the degree of informationization in a country.
Sensing technology is a multidisciplinary modern science and engineering technology that acquires information from natural sources and processes (transforms) and recognizes them.
It involves activities such as planning, development, manufacturing/building, testing, application and evaluation of sensors (also known as transducers), information processing and identification.
Access to information depends on a variety of sensors that have sensors of various physical quantities, stoichiometry or biomass.
According to the convexity theorem of information theory, the function and quality of the sensor determine the information quantity and information quality of the sensing system to obtain natural information, which is the first key to the construction of high-quality sensing technology system.
Information processing includes signal pre-processing, post-processing, feature extraction and selection.
The main task of identification is to identify and classify processed information.
It uses the association model between the identified (or diagnosed) object and the feature information to identify, compare, classify and judge the input feature information set.
Therefore, sensing technology follows information theory and system theory.
It contains many high-tech and is widely used by many industries.
It is also the basic condition for the development of modern science and technology and should be given enough attention.
In order to improve the productivity (or reduce the running time) and product quality of the manufacturing enterprise and reduce the product cost, the basic requirements of the industry for sensing technology can be reliably applied to the site to fulfill the specified functions.
