A sensor (English name: transducer/sensor) is a detection device that can sense the information being measured and convert that information into electrical signals or other required forms of information output according to certain rules, to meet the requirements for information transmission, processing, storage, display, recording, and control.
The characteristics of sensors include miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. It is the primary link for achieving automatic detection and automatic control. The existence and development of sensors have given objects 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.
