The sensor is a detection device that can sense the measured information, and can convert the sensed information into electrical signals or other required forms of information output according to a certain rule to meet the transmission, processing, storage and display of information The characteristics of sensors required for recording, recording and control include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of the sensor gives the object a sense of touch, taste and smell, and slowly makes the object alive. According to its basic perception function, it is generally divided into ten categories: heat sensitive elements, light sensitive elements, gas sensitive elements, force sensitive elements, magnetic sensitive elements, humidity sensitive elements, acoustic sensitive elements, radiation sensitive elements, color sensitive elements and taste sensitive elements.
