**问题：**我面临的问题是ECG传感器读数一直显示为0，发送到Firebase的数据不准确。我已经检查了连接，它们似乎是正确的。
其他信息：

• 我已验证ECG传感器是否接收到正确的电源电压。
• 我还检查了导联脱落检测引脚（leadOffPin 1和leadOffPin 2），它们似乎工作正常。
• 已成功建立与Firebase的Wi-Fi连接。
• 具体问题：**

1. ECG传感器无法提供有效读数的可能原因是什么？如何解决此问题？
   1.如何确保发送到Firebase的数据准确地代表ECG传感器读数？
   1.在将ECG传感器与ESP 32和Firebase集成时，是否有我应该注意的常见陷阱或最佳实践？
