摘要
本室内空气质量检测系统,采用Cortex-M3为内核的STM32C8T6作为微处理器,主控板搭载SHT20温湿度传感器、PM2.5激光传感器,能够快速、准确地将室内温湿度值、PM2.5含量检测出来,并通过段式LCD液晶屏显示,同时根据检测出的PM2.5数值,利用CC2541蓝牙模块串口透传功能,发送自定义指令,让子模块执行相应功能。
This indoor air quality testing system adopts Cortex-M3 as the core microprocessor STM32C8T6 as the core CPU embedded controller. The master plat carries SHT20 temperature and humidity sensor,PM2.5 laser sensor ,able to quickly and accurately detect values, the sections of LCD can display that, at the same time ,according to the detected PM2.5 values, the CC2541 bluetooth module with its serial transfer function to send custom commands to the child module performs ,that will do the corresponding function.
