Arduino 如何更换传感器的功能？

我正在制作一个设备，可以监测我的水族馆的水参数。但问题是，当我的pH计传感器（dfrobot）和溶解氧传感器（dfrobot）位于同一水体中时，pH传感器似乎接地（idk如何称呼错误），它读取的pH值较低。几乎为负值。但当我把它们放在不同的容器中时，pH传感器工作正常

我的DO传感器没有问题

正如问题所述。我设法做了一个算法，可以交替读取两个传感器的读数，这样它们就可以在另一个传感器之后工作。 我曾尝试添加延迟和if-else条件来交替传感器读数，但没有成功。 我在寻找一些类似于非提前调度的东西，但问题是，他们必须在另一个轮到他们后再次循环。我的错是我不能让它发生

这是pH传感器和DO传感器的原始逻辑

否则如果（（phValue>phTH_L）和（phValue）您是否尝试过将传感器的探头进一步分开？如果它们以某种方式通过水连接，这应该会解决或至少会降低效果，我也在考虑。明天将尝试，因为d.o传感器的导线更长。我也在考虑使用rtc使其基于时间，以防止另一个同时运行。这不可能在代码中解决，所以我可能会使用rtc来实现它。
