摘　　要：为了实时准确地检测出大气中PM2.5值,采用单片机STC89C52为控制中心,以PMS7003传感器测量空气固体颗粒浓度,SHT11检测大气的温度和湿度,LCD1602显示屏显示被测参数值。设计了一种大气质量实时检测装置,该装置不仅能实时检测大气中PM2.5和PM10浓度,还可以检测环境的温湿度,同时对PM2.5具有报警功能,其报警上下值限设定能直观提醒当前的污染级别。In order to detect the PM2.5 value in the atmosphere in real time, the MCU STC89 C52 was used as the control center, the PMS7003 sensor was used to measure the concentration of air solid particles, and SHT11 detects the temperature and humidity of the atmosphere. The LCD1602 display displays the values of the measured parameters. A real-time atmospheric quality detection device was designed, which can not only detect PM2.5 and PM10 concentrations in the atmosphere in real time, but also detect the temperature and humidity of the environment, and at the same time has an alarm function for PM2.5. Its alarm upper and lower value limit setting can intuitively remind the current pollution level.
