摘　　要：为准确监测日益严重的雾霾天气,基于STM32F407开发系统,结合n RF24L01无线通信模块、GSM通信模块、PM2.5传感器模块和相应的外围硬件及软件设计了无线智能网络监控系统,并采用数字滤波技术的中位值平均滤波算法对PM2.5传感器所采集数据进行处理.结果表明:检测数据结果准确,可在液晶屏上实时显示PM2.5浓度,若超过预定值则GSM无线通信模块可以短信和电话振铃方式通知个人用户.To correctly detect increasingly serious smog, a system based on STM32F407 has been proposed. Based on the STM32F407 development system, the wireless intelligent network monitoring system was designed with the nRF24L01 wireless communication module, the GSM communication module, the PM2.5 sensor module and tile corresponding peripb-eral hardware and software. The median filtering algorithm based on the digital filtering technique was proposed for the PM2.5 sensor collecting data for processing. The results show that the test data is accurate, and PM2.5 concentration is displayed in the LCD screen in real time. If the predetermined value is exceeded, the individual user will be notified by GSM wireless communication module with GSM and telephone ringing.
