Design and construction of computer laboratory security monitoring system based on STM32 microcontroller

Abstract

A multi parameter monitoring system based on STM32 microcontroller was designed to address the security risks in computer laboratories, achieving dynamic monitoring and real-time alarm of the laboratory environment to improve the safety and management level of the laboratory. Parameters such as humidity and gas concentration were used to monitor the laboratory environment. The STM32 microcontroller serves as the control core of the system, controlling and collecting data from various sensors through analog input and output ports. At the same time, the system adopts network communication technology to transmit data to the upper computer for processing, achieving abnormal alarm function. The experiment shows that the system can accurately monitor the environmental parameters of the laboratory and transmit data to the host for processing through network communication technology, achieving abnormal alarm function. During the real-time monitoring process, the system can timely detect and alert laboratory safety hazards, effectively improving the safety and management level of the laboratory. The system has achieved real-time monitoring and abnormal alarm of the laboratory environment, improving the safety management level of the laboratory. This system is practical and feasible, and can provide reference for laboratory safety management.
