PMS7003 PM2.5测试仪,带SHT20温湿度 STM32源码

ID:86777 · 发表于 2017-7-20 14:01

由于网上的PM2.5测试仪质量不一，多数测试仪传感器只能定性，而不能精确定量，而且价格还很贵，所以在家没事做了个PM2.5测试仪，带温度显示
配件：
1、空气质量传感器为攀腾第七代PMS7003传感器
2、温湿度传感器为SHT20
3、单片机STM32F103C8T6
屏幕各界面显示数据：空气质量指数，PM2.5.PM0.3.PM0.5.PM1.0.PM2.5.PM10颗粒数，含量以及温湿度

特别提示：代码我只上传了攀藤7003传感器的官方测试代码，希望各位电子爱好者勇于探索，功到才能自然成。

单片机源程序如下:
