监测pm2.5，这是用于蓝牙传感器监测模块测的数据在LCD上显示(Monitoring PM2.5,This is the data used for the Bluetooth sensor monitoring module to display on the LCD)

利用STM32单片机连接PM2.5传感器，检测PM2.5和PM10，采用modbus方式受上位机控制。(PM2.5 sensor is connected with STM32 single chip computer to detect PM2.5 and PM10. The upper computer controls PM2.5 and PM10 by Modbus mode.)

stm32+GP2Y1010AU,通过屏幕显示pm2.5的值，stm32的A1口连接传感器的LED端口，A0连接数据口！(60/5000 Stm32 +GP2Y1010AU displays the value of pm2.5 through the screen. The A1 port of stm32 connects to the LED port of the sensor, and A0 connects to the data port!)
