Laboratory information management based on the technology of Interact of things technology is the development trend of digital and information technology education in our country and the inevitable choice. Through the fiLnher study of the current situation of laboratory management in colleges and universities and the characteristics of the Internet of things technology, this paper introduces the concept of Interact of things tec^mology, history and current situation of the development. With the most representative IOT architecture and Ubiquitous ID IOT system as an example, analyzes the RFID technology, sensor network and detection technology, intelligent technology and characteristics of Nanometer technology. Analysis the technical foundation for the development of the campus Interact of things, and give the Internet of things technology in the application of the laboratory management technology. 展开更多
