我必须承认,这篇文章只是与Grafana和InfluxDB一起玩的借口。InfluxDB是一个很酷的数据库,专门用于处理时间序列数据。Grafana是一个用于时间序列分析的开源工具。...这个想法是:一个Arduino设备(ESP32向Mosquitto服务器发出MQTT事件。我将使用电位计来模拟一个传感器。
To write data to the Serial Monitor, you use the print() or println() methods on the Serial instance. Serial.println("ESP32 is ready. Please enter a message:"); You can also send data from the Serial Monitor to the ESP32. To read that data, you can use the read() method. To ...
