本设计： 基于Labview设计空气质量监测系统_STM32F103C8T6（程序 原理图 PCB） 原理图：Altium Designer 程序编译器：keil 5 编程语言：C语言 编号C0028
本设计结合下位机和上位机实现系统监控的功能。使用上位机软件Labview设计虚拟仪器，采用下位机STM32F103C8T6单片机控制。主要由温湿度传感器、光传感器、显示器、无线传输模块等组成。温湿度传感器可收集室内温湿度，然后反馈给单片机，单片机处理后在显示器上显示相关参数。同时，光传感器的工作原理与温湿度模块相同。 1.上位机实现功能 通信波特率设置为115200，上位机通过USB无线串口转NRF24L01模块接收下位机传输的环境参数信息，实时显示当前的温度、湿度和光强。当环境参数大于设定阈值时，上位机显示界面中的报警指示灯亮起，下位机蜂鸣器报警模块响起，启动冷却模块。当环境参数恢复正常时，报警自动取消，冷却模块停止工作。 2.下位机实现功能 单片机STM32F103C8T6通过DHT11温湿度传感器和光敏二极管通过当前环境中的温湿度和光强信息分别收集OLED屏幕实时显示，收集到的环境数据通过NRF24L01无线通信模块实时发送到上端。当环境参数大于设定阈值时，蜂鸣器模块报警，雾化器模块冷却。当环境参数恢复正常时，报警自动取消，雾化器模块停止工作。
