Sensors are devices or instruments that can sense specific measured quantities and convert them into usable output signals according to certain rules. Typically, the measured quantities are non-electrical physical quantities, and the output signals are generally electrical. The world today is facing a new technological revolution, the foundation of which is information technology, and sensor technology is considered one of the three pillars of information technology. Some developed countries regard sensor technology as being on par with communication technology and computer technology.
With the development of modern science, sensor technology, as an emerging discipline closely related to modern science, has also developed rapidly. It is increasingly utilized in industrial automation measurement and detection technology, aerospace technology military engineering, medical diagnostics, and other fields, while also promoting the development of various disciplines.
In general, the characteristics of sensors include: miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They are the primary link in achieving automatic detection and automatic control. The existence and development of sensors have endowed objects with tactile, taste, and olfactory senses, making them gradually come to life.
Typically, sensors are classified into ten categories based on their basic sensing functions: thermal sensitive elements, light sensitive elements, gas sensitive elements, force sensitive elements, magnetic sensitive elements, humidity sensitive elements, sound sensitive elements, radiation sensitive elements, color sensitive elements, and taste sensitive elements.
