2019 sensor market continues to grow

China's sensor industry is at a critical stage of development from traditional sensors to new sensors, reflecting the general trend of new sensors toward miniaturization, versatility, digitization, intelligence, systematization and networking. After years of development, sensor technology can be divided into three generations.

The first generation is a structured sensor that uses structural parameter changes to sense and transform signals.

The second generation is a solid state sensor developed in the 1970s. Such sensors are composed of solid elements such as semiconductors, dielectrics, magnetic materials, and the like. It is made using certain properties of the material. For example, thermoelectric effects, Hall effects, and photosensitivity effects are used to fabricate thermocouple sensors, Hall sensors, and photosensors, respectively.

The third generation of sensors is a smart sensor that has just developed in the future. It is a combination of microcomputer technology and detection technology, which makes the sensor have certain artificial intelligence. The Internet of Things is used to collect or acquire various physical quantities, chemical quantities, and biomass in nature. The sensor converts various physical quantities, chemical quantities, and biomass in nature into measurable electrical signals. As a whole system, the concept of the Internet of Things, at the three levels of perception, transmission and application, sensors must complement each other for the Internet of Things.
