Design of Laboratory Virtual Environment Monitoring System Based on Digital Internet of Things Technology

In order to meet the requirements of laboratory ventilation and exhaust purification, it is necessary to monitor the laboratory environment in real time. Effective control of all environmental parameters of animal experimental equipment is a key condition to ensure the smooth progress of animal experiments. To address this issue, this paper proposes to construct a virtual laboratory environment monitoring system based on digital Internet of Things (IoT) technology, which can monitor the temperature and humidity, noise level, lighting, air quality and radiation detection in the laboratory in real time, and can be used to ensure that the environment of animal laboratories meets the standards. The system collect real-time data from the laboratory environment using indication sensors and display it on an OLED screen. The system includes threshold setting methods that activate support services such as audible alarms, temperature and humidity monitoring, and fan activation in the event of abnormal conditions. The system take advantages of real-time monitoring from multiple hosts in different locations, unmanned operation and large-scale data storage. The final experimental results show that the sensitivity and specificity of the laboratory environment monitoring system based on this technique are 95% and 93% respectively, which are higher than other algorithms.
