The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-functionality, systemization, and networking. It not only promotes the transformation and upgrading of traditional industries, but also may establish new industries, thus becoming a new economic growth in the 21st century. point. Miniaturization is based on microelectromechanical systems (MEMS) technology and has been successfully applied to silicon devices as silicon pressure sensors.
It is a detecting device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to meet the information transmission, processing, storage, display, Requirements such as recording and control.
Sensors have long penetrated into extremely ubiquitous fields such as industrial production, space development, ocean exploration, environmental protection, resource surveys, medical diagnostics, bioengineering, and even cultural relics protection. It is no exaggeration to say that from the vast space, to the vast ocean, to various complex engineering systems, almost every modern project can not be separated from a variety of sensors.
