Based on the National IOT Information Technology and System Engineering Experimental Teaching Center and the Key Laboratory of Laser and Infrared System Integration Technology of the Ministry of Education, the innovation project of optoelectronic engineering based on infrared sensing Internet of Things is carried out. The main contents include: (1) Hands-on experimental projects, such as optical basic experiments and optoelectronic detection basic experiments, enable students to accept the basic knowledge of photoelectric sensing Internet of Things in a subtle way. Based on this, the planning, design and implementation of infrared IoT sensing system experiments are carried out. (2) Invite experts from optoelectronic high-tech companies to make reports on the progress and application of the Internet of Things, and guide students to pay attention to the frontiers of the industry. (3) Visiting the internship base of Shandong University, such as Hisense Group and the National Deep Sea Base, to experience the innovation process of products and equipment of enterprises and research institutes, and the application of photoelectric sensing Internet of Things. Through the implementation of the project, students can initially grasp the preliminary knowledge of optoelectronic engineering, experience the innovation process, enhance the sense of innovation, and improve engineering literacy and innovation ability.
