校内竞赛做了一个PM2.5测量仪，采用pm2.5传感器DSM501A测得PM2.5的浓度并把它转化为脉冲量，通过51单片机检测脉冲量并把它转化为数字量，经过换算，送到LCD1602进行显示。 (School race made ​ ​ a PM2.5 measuring instrument, using pm2.5 sensor DSM501A measured concentrations of PM2.5 and put it into pulses, pulses detected by the microcontroller 51 and convert it to digital, after conversion, send to LCD1602 display.)
