摘要
基于STM32的PM2.5检测系统,该PM2.5检测系统以STM32 MCU为控制中心,并由DSM501灰尘传感器测量空气粉尘浓度,1602LCD显示屏显示当前空气中PM2.5浓度,当空气中PM2.5浓度超过所设限定值时启动蜂鸣器自动报警。具有电路结构简单,硬件成本低,外观小巧,便于携带等优点。
The design of PM2.5 detection system based on STM32,the PM2.5 detection system based on STM32 MCU control center.The air dust concentration is measured by the DSM501 dust sensor,1602 LCD display shows the current PM2.5 concentrations in the air,when the air PM2.5 concentrations exceed the set limit value starting buzzer alarm automatically.This design has simple circuit structure,low hardware cost,compact,easy to carry,etc.
