Description

technical field [0001] The invention relates to the field of digital campus display products, in particular to an interactive blackboard with automatic brightness adjustment. Background technique [0002] The interactive blackboard is a high-tech electronic product that replaces the traditional blackboard. It integrates liquid crystal display technology and computer technology, making information processing more convenient and teaching calculations more vivid. Interactive blackboards are more often used in smart classrooms. Smart classrooms are based on IoT technology, so they can be built into an IoT application scenario, which can be used not only for students to conduct innovative experimental research, but also for teachers to carry out scientific research. The personnel attendance system in the smart classroom can be used to judge whether there are people in the classroom. If there is no one in the classroom, all systems in the classroom are turned off; otherwise, they ...
