The sensor application course is a professional basic course for automation, Internet of Things, electromechanical and other majors in higher vocational colleges. It mainly involves important knowledge content such as the principle, characteristic parameters, usage methods and measurement circuits of sensors. After studying the sensor course, students will master the characteristics and usage methods of common sensors and be able to solve problems encountered in actual measurements. Sensor application is a very practical course, so it is difficult to achieve good teaching results using traditional classroom teaching methods during the teaching process.
Project teaching method enables students to complete the design and implementation of project plans in groups under the guidance of teachers and finally complete the project tasks [1]. In the entire teaching process, teachers only play a guiding and auxiliary role, and students are the real project completers. By completing the project, theory and practice can be combined, which can not only achieve knowledge understanding and application, but also improve skills. It is a reasonable teaching method. Therefore, project teaching method is an effective way to improve students' sensor skills.
In human society, industry, agriculture, commerce, scientific research, national defense, medical care and other fields are closely related to temperature. Therefore, temperature sensors are a must-know part of the sensor course [3]. How to implement the project teaching method in the temperature sensor course? The following steps need to be clarified: determine the project, prepare knowledge, establish the plan, implement the task, debug the experiment, write the project report, and check and evaluate.
Determining the content of the project is the most important part of project teaching, which is mainly determined based on the student's training plan and relevant information of the syllabus [4]. The project design should organically combine theoretical knowledge with practical content, allowing students to learn sensor-related knowledge in the project while also having the operability of engineering practice. In the chapter on temperature sensors, students should focus on mastering the working principles and usage methods of several temperature sensors, understand their working characteristics and important parameters and measurement circuits, and focus on mastering the typical applications of thermocouples and thermistors. At the same time, students also need to be able to master the use of integrated circuit chips in actual applications.
