我们常说的D1其实全名是WeMos D1,有ARDUINO兼容版和MINI版 D1 UNO版其实有个地方需要注意就是它没有完整的模拟输入,相比基于AVR单片机的UNO之类的不太一样。 这个位置是空脚 这是UNO到D1的映射,有些地方可以直接通过修改代码实现 然后还需要下载一个压缩包 ...

将DHT11连接到Arduino UNO 将DHT22连线至Arduino UNO 这样,您现在就可以上传一些代码并使它正常工作了。 Arduino代码–在串行监视器上打印值 DHT11和DHT22传感器具有自己的单线协议,用于传输数据。该协议需要精确的时间。幸运的是,我们不必为此担心,因为我们将使用DHT库,该库几乎处理了所有事情。
