Sensor Principles and Technology is compiled by the teaching team at Guangxi Electromechanical Engineering School. It can serve as a textbook for vocational college majors in automation, electrical, electromechanical, and electronics, as well as related fields, and it can also be used as professional training material for relevant positions. It is organized around eight core areas, covering basic sensor modules such as temperature, force and pressure, flow, displacement, photoelectric, and gas detection, and extending to new sensor application technologies. By integrating emerging industry technologies, process standards, and digital resources, it has built a curriculum system that deeply fuses theory with practice.
