Speed sensors require paired operation. Below are detailed explanations about sensors: 1. Definition: A sensor is a detection device that can perceive measured information and convert it into electrical signals or other required forms of information output according to specific rules, meeting requirements for information transmission, processing, storage, display, recording, and control. 2. Features: Miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. It serves as the primary link in achieving automatic detection and control. The existence and development of sensors enable objects to possess senses like touch, taste, and smell. Typically categorized by basic sensing functions into ten major types: thermal, photosensitive, gas-sensitive, force-sensitive, magnetic-sensitive, humidity-sensitive, sound-sensitive, radiation-sensitive, color-sensitive, and taste-sensitive elements.
