c++ - 我想使用 Nodemcu 和 blynk 连接两个 yf-s201 水流传感器，一个作为流入，另一个作为流出

Question

这主要是我在谷歌上找到的代码的复制粘贴，

我想使用 2 个水流传感器制作一个项目，其中 inflow() 显示我吸入了多少升，outflow() 显示流出了多少升。

这是我达到的程度，需要代码方面的帮助，我不是高级编码人员，因此非常感谢描述性代码和支持。另请参阅 maincode()，在该部分中我试图实现一个循环，我的意思是如果传感器 1 为高，则应显示传感器 1（流入（））输出，如果传感器 2 为高，则应显示传感器 2（流出（） ） 输出。

面临的问题：当我同时调用流入（）和流出（）时，输出不起作用，一个函数起作用，（我认为它与板的中断引脚有关？）。
