我在串行监视器输出中看到了什么？

Question

这是我使用 HC-SR04 超声波传感器进行运动检测的代码，使用 Sinric Pro 运动传感器草图并与我为超声波传感器找到的 Intructables 代码相结合。但是，当我将代码上传到 NodeMCU 板时，我在串行监视器中得到以下输出：

我不确定我尝试组合这两个代码的方式是否有问题，或者是否有其他问题。有人可以通过识别我的错误或帮助我找到/创建新代码来帮助我吗？

1. 这可能是因为您的 Arduino 串行监视器速度设置为与草图中设置的速度不同 (115200)。尝试将 Arduino 串行监视器速度设置为 115200

2. 您正在尝试使用超声波传感器而不是运动传感器（PIR/微波）来检测运动，这可以完成但很麻烦。您将需要添加额外的逻辑来停止发送重复的运动检测事件。因此，如果您是初学者，请尝试使用运动传感器而不是超声波传感器。您可以在这里找到运动传感器教程：https://help.sinric.pro/pages/tutorials/motion-sensors/HC-SR501-HC-SR505-AM312-HC-SR312

有一个超声波传感器教程可以帮助您了解是否仍要使用超声波传感器：https://help.sinric.pro/pages/tutorials/custom-device-types/ultrasonic-sensor/ HC-SR04。尝试在没有 Sinric Pro 的情况下编码来检测运动，然后尝试集成它
