摘　　要：以STM32F103C8TB单片机为控制器,通过传感器模块获得当前室内温湿度、细小颗粒物(PM2.5)浓度、甲醛及挥发性有机物(VOCs)含量;通过LoRa通信模块将各个节点采集的数据发送至监控中心;监控中心将收到的数据进行融合处理并在液晶显示屏上显示。若甲醛或VOCs含量超标,则启动智能调节模块;若PM2.5浓度超标,则启动报警装置。经测试,智能调节模块性能稳定,能有效吸收、降解多种有机物,实现了监测、调节与报警一体化的智能控制功能。The system uses STM32F103C8TB micro-control unit(MCU)as the controller to obtain main current indoor temperature and humidity,fine particulate matter(PM2.5)concentration,formaldehyde and volatile organic compounds(VOCs)content through the sensor module;the data collected by each node is sent to the monitoring center through the LoRa communication module.The monitoring center fuses the received data and displays it on the LCD.If the formaldehyde or VOCs content exceeds the standard,the adjustment module will be intelligently activated;if the PM2.5 concentration exceeds the standard,the alarm device will be activated.Test show that the intelligent adjustment module has stable performance and can effectively absorb and degrade various organic substances.The system realizes the intelligent control function of monitoring,regulation and alarm integration.
