A sensor (English name: transducer/sensor) is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other desired forms of information output according to certain rules, to meet the requirements of information transmission, processing, storage, display, recording, and control.
The characteristics of sensors include: miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. It is a primary link in achieving automatic detection and automatic control. The existence and development of sensors give objects tactile, taste, and olfactory senses, making them gradually come to life. Typically, they are divided 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.

Features of this book:
This book is based on practical engineering projects as a carrier, using task-driven teaching. At the same time, it emphasizes the comprehensive application and design of sensors.
1. Written using the teaching approach of practical engineering projects, each project is a specific task that has been verified through practical engineering use.
2. In each project, the application of sensors is the main line, designing specific application circuits; each sensor’s application circuit is placed at the front, highlighting the application circuit of the sensor.
3. The tasks in industrial production are the main line, with necessary knowledge points woven into the completion of the tasks.
4. During the writing process, emphasis is placed on simplifying theoretical content, reducing theoretical derivation of formulas, and theoretical analysis of processing circuits.
5. The book contains many images taken from actual sites, enhancing practicality and intuitive effects.
