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 principles, characteristic parameters, usage methods and measurement circuits of sensors. After taking the sensor course, students will master the characteristics and usage of common sensors and be able to solve problems encountered in actual measurements. Sensor application is a very practical course, so during the teaching process, it is difficult to achieve good teaching results using traditional classroom teaching methods.

The project teaching method allows students to complete project plan design, implementation and final project tasks in groups under the guidance of teachers [1]. In the entire teaching process, teachers only play a guiding and supporting role, and students are the real completers of the project. By completing the project, it is a reasonable teaching method to combine theory and practice, not only realize the understanding and application of knowledge, but also improve skills. Therefore, project teaching method is an effective method to improve students' sensor skill level .

In human society, various fields such as industry, agriculture, commerce, scientific research, national defense, medical and health care are closely related to temperature. Therefore, temperature sensors are a part that must be mastered in the sensor course [3]. How to implement the project teaching method in the temperature sensor course? The following steps need to be clarified: project identification, knowledge preparation, plan establishment, task implementation, experimental debugging, project report writing, inspection and evaluation, etc.

Determining the content of the project is the most important link in project teaching, and is mainly determined based on the students’ training plan and relevant information on the teaching syllabus [4]. The project design should organically combine theoretical knowledge with practical content, allowing students to learn sensor-related knowledge during the project while also being operable in 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, important parameters and measurement circuits, focus on mastering the typical applications of thermocouples and thermistors, and at the same time, in practical applications Students also need to be able to master the use of integrated circuit chips. In order to achieve this teaching goal, we take making a simple thermometer as the project topic of the course, allowing students to personally select the temperature sensor and complete the connection of the measurement circuit and the overall design of the system.
