Features: This book integrates scientific rigor, advanced technology, systematic structure, and practicality, and has the following characteristics: , it comprehensively and deeply elaborates on the new technologies and achievements in the field of single-chip intelligent sensors at home and abroad, providing detailed introductions to the working principles, typical applications, interface technologies, and detection technologies of single-chip intelligent sensors for measuring parameters such as temperature (including temperature compensation), humidity, pressure, rotation speed, angular velocity, acceleration, ultrasonic waves, magnetic field, current, liquid level, smoke, turbidity, conductivity, and ambient brightness. Additionally, it provides detailed introductions to internationally newly launched software-based virtual sensors, single-chip networked intelligent sensors, single-chip fingerprint sensors, and other chips, fully reflecting the latest domestic and international technological achievements in this field. Second, the structure is rigorous, the organization is clear, and the logic is strong. For example, in Chapter 4, the performance characteristics and product classifications of humidity sensors are introduced first, followed by the circuit design of relative humidity meters based on humidity-sensitive resistors and humidity-sensitive capacitors, then the principles and applications of voltage-output, frequency-output, and frequency/temperature-output integrated humidity sensors are explained in sequence, and finally, the principle and application of a newly launched single-chip intelligent humidity/temperature multi-parameter sensor are introduced. The content progresses from the surface to the core, from simple to complex. The chapters also maintain relative independence, allowing readers to either read the entire book or select specific chapters. Third, it has high practical value. The book provides application circuits for various new single-chip intelligent sensors, which offer significant reference value for readers in developing new sensor systems and measurement and control systems using single-chip intelligent sensor chips. Fourth, it is rich in information and broad in scope, making it easy for readers to generalize and apply flexibly. The book introduces hundreds of integrated sensor product models. From a practical perspective, it comprehensively and systematically elaborates on the principles and applications of various new integrated intelligent sensors internationally. The book consists of 13 chapters. Chapter 1 is an overview of single-chip integrated intelligent sensors. Chapters 2 to 12 introduce the working principles and application technologies of single-chip intelligent temperature sensors, integrated temperature compensators, integrated humidity sensors, silicon pressure sensors and signal conditioners, networked intelligent pressure sensors, integrated magnetic field sensors, integrated rotation speed sensors, single-chip acceleration sensors, integrated ultrasonic sensors and ultrasonic interference detectors, integrated magnetic field sensors, single-chip fingerprint sensors, and integrated current sensors and transmitters. Chapter 13 introduces the typical applications of special integrated sensors such as liquid level, smoke, turbidity, gyroscopes, and ambient brightness. This book is the first specialized work in China to introduce integrated intelligent sensors. The book features novel themes, rich content, and an accessible yet in-depth approach, combining scientific rigor, advanced technology, and high practical value. It is suitable for electronic, computer, and electrical engineering technicians, as well as serving as a textbook for relevant majors in higher education institutions.
