The laboratory environment has a very significant impact on the safety and life of electronic instruments and equipment, as well as the fire safety of the laboratory. Traditional laboratory environmental monitoring requires personnel to be on duty and inspection for 24 hours, and the labor investment and installation and wiring costs are very high. In response to the above problems,uses high-performance and low-power ionic smoke sensor NIS-07 and temperature and humidity composite sensor DTH11 to collect environmental data, uses a wireless network module to complete the data transmission, and uploads the collected data to the server through the microprocessor At the same time, the PID control algorithm based on BP neural network is used to realize online dynamic temperature and humidity control. The server uses Tomcat web server and MySQL database for data storage, and realizes the storage, analysis and processing of sensor data and the update of client data through the Java programming language. The client monitors the laboratory environment in real time through the Web page or APP, so as to realize accurate and efficient remote centralized management of the laboratory environment.
