Classroom teaching behavior is gradually diversified, and the concept of wisdom classroom is constantly put forward in the industry. Wisdom classroom, as an extension and application of intelligent low-voltage electrical appliances, extends the characteristics of smart grid to the user side. Based on advanced information, control, sensing, new energy storage and transmission technology, smart grid is characterized by deep information, comprehensive interaction, electric energy cleaning, asset efficiency, regulation incentive, and has the ability of intelligent monitoring, diagnosis, communication, control, decision making and self-healing in all directions, whole process and all elements. wisdom classroom, using embedded single-chip computer technology based on STM32, so that the ordinary classroom also has the ability to monitor the environment and electrical parameters. This paper discusses the electrical and environmental monitoring system of wisdom classroom based on STM32 in detail. The hardware module design of the system mainly includes five parts: MCU module, OLED display module, BL0940 electric parameter mon
