TCS34725在2个月后停止

Question

目前，我正在一个需要监视某些传感器的项目中。我使用的传感器之一是TCS34725 RGBC光传感器。使用Blynk，我将数据记录到数据库中并在浏览器仪表板和Blynk应用程序上显示。运行约2个月后，停止读取该值。

    Blynk.run();
    timer.run(); // Initiates BlynkTimer
    ArduinoOTA.handle();  // For OTA

}

此代码有效期为2个月。除TCS34725之外，我在连接到WeMos D1 mini的电路中配有SHT31-D，7805 5V稳压器和3030 5V风扇。唯一发生过的事故是盒子（我把所有电路都放到了那里）掉了10-20厘米，仍然可以工作数周。

我唯一能得到的值是当我重置Wemos D1 mini时，它将在发送0之前发送1读数。

您的计时器可能溢出并从零开始。在BlynkTimer的source中，您可以看到此计时器值为无符号长整数。您可以通过查看文档轻松地找到unsigned long的大小，但更简单的方法是在arduino代码中执行以下操作：
