[求助] 大神帮忙看下气象站代码串口无数据 |
麻烦群里的大神帮忙看下小弟下面的气站站代码,传感器由DHT11,BMP180,PM2.5组成的 问题: 1接好传感器串口输出的数据显示传感器检测的温度 气压 都是零,请问大神代码哪里有问题 2我想上传乐联网,但是怎么也上传不到乐联上。 麻烦群里大神帮忙修正下代码,感谢。 #include <LeweiClient.h> #include <SPI.h> #include <Ethernet.h> #include <dht11.h> #include <SFE_BMP180.h> #include <Wire.h> //dht11 dht11 DHT11;
