Abstract: In view of the problems existing in the traditional teaching of sensors and detection technology at present, it is proposed to take the“Internet +”competition as the support, adopt the project-based teaching mode, integrate theory teaching, hardware construction, and software programming, guide students to learn theoretical knowledge and installation skills in the process of doing, make physical results that can be automatically detected through the correct selection and use of sensors, and in the process of learning and doing, deeply learn and practice professional knowledge and skills related to sensors, detection technology, mechanical engineering, software programming, etc. In order to overcome the practical problems such as the difficulty in purchasing and the professionalism of programming software caused by the miscellaneous and numerous parts, Arduino kits are purchased in a one-stop manner and programmed with the graphical programming software linkboy. Visually simulate hardware construction and program operation on the programming interface, saving the cost of simulation software procurement. Through practice and exploration, a teacher model worthy of promotion has been formed and profound teaching reflection has been formed.

Key words: Sensor and detection technology, Project-based teaching, Learn to be one, Teaching mode, Teaching innovation, Arduino suite
