Sensors are detection devices capable of sensing measured information and converting it into electrical signals or other required forms of information according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. According to the Chinese National Standard GB7665-87, a sensor is a device or system that can sense specified measured objects and convert them into usable signals according to certain rules (mathematical function laws). Typically, sensors consist of sensitive elements and conversion elements. Sensors are a general term for devices or systems that can sense specified measured objects and convert them into usable output signals, usually in the form of electrical quantities. Sensors are devices or systems that can sense specified measured objects and convert them into usable output signals according to certain rules. They usually consist of sensitive elements and conversion elements, where the sensitive element refers to the part of the sensor that can directly sense (or respond) the measured object. The conversion element refers to the part of the sensor that can convert the measured object, which is sensed by the sensitive element, into electrical signals for transmission and (or) measurement. The characteristics of sensors include miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They are the primary link for realizing automatic detection and control. Sensors are generally classified according to their basic sensing functions into thermosensitive elements, photosensitive 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, among others.
