Abstract: With the rapid development and wide application of the internet of things technology, the urgent need for the training of the talents of internet of things in colleges and university.According to the characteristics of the internet of things engineering, this paper puts forward the method of constructing the hierarchical experiment teaching system for the internet of things by practice to help the students master the knowledge, and realize the fusion of interdisciplinary knowledge. According to the characteristics of the major, this paper proposed the construction of a hierarchical experiment teaching system. The hierarchical teaching system is divided into three ca tegories: basic experiment, comprehensive experiment and innovative experiment. And this paper designed experiment content for each part of the hierarchical teaching system. The experimental teaching system combines theoretical knowledge and practice tightly,pays more attention to the cultivation of students basic quality and innovation ability, it will achieve a good teaching effect.
