This paper describes the design of a miniature PM particle detector to address the issues of accuracy and efficiency in detecting PM values in atmospheric environments.It proposes a detection method based on the piezoelectric effect of quartz crystals,which uses QCM particle detection technology.It designs and develops a micro particle detector circuit control chip,establishes a multi particle sensing decoupling model,builds a QCM circuit simulation experimental system,and realizes the detection of air PM values using QCM sensors.
