基于STM32的PM2.5监控系统的设计与实现

AbstractThe world today is a modern information world.We can use existingtechnology to design some equiPMent that can detect the surroundingenvironment.which is the most direct and effective method to reflect thecurrent environmental situation quickly and accurately.The beauty ofindoor environment is the demand of contemporary people's housing.Inorder to pursue the beauty of indoor environment,people decorate housesby using a large number of synthetic chemical materials,which can greatlyimprove and retain the beauty of the house,but it will cause the problemthat the indoor will retain harmful gases,which will increase the risK.As aresult of environmental changes and abnormal climate the dust layerbecomes increasingly polluted,often causing respiratory system diseases,such as rhinitis.From this we can see that the concentration of PM2.5 in ouratmospheric environment will continue to be watched by humans because itis closely related to our health.Our design most needs to preparePM2.5ZPH01 detection sensor STM32F103C8T6 single chipmicrocomputer and 1602 LCD these three design devices.Keywords:PM2.5 concentration STM32 microcontroller LCD MonitorIndoor environment
