ABSTRACT

Traditional university laboratory safety management relies on manual inspection, leading to slow response, inadequate supervision and incomplete data, which brings hidden dangers to labs with precision instruments and hazardous chemicals. To solve these problems, this paper designs an intelligent laboratory monitoring system based on STM32F103C8T6 single-chip microcomputer with a modular structure. The system integrates multi-type sensors for real-time collection of temperature, humidity, illumination, smoke concentration and intrusion signals, and is equipped with OLED display, sound-light alarm and ESP8266 Wi-Fi modules. It realizes local data processing and real-time early warning, and uploads monitoring data to the cloud platform for remote visualization management. Physical tests show that the system runs stably with sensitive response, triggering alarm and uploading abnormal data within 1 second, and realizing accurate synchronization of local and cloud data. This system effectively improves the safety protection and intelligent management level of laboratories, and provides a practical solution for the intelligent transformation of laboratory safety management.
