nodered通过串口监控硬件,依赖于usb数据线,而要实现无线远程数据信息监控,就涉及到物联网功能,而node-red提供的可以通过mqtt协议节点来实现该目的。 这里选自板载wifi功能的esp32芯片的掌控板,并且可以其单片机程序可以通过图形化编程实现。 mqtt中继服务器可以使用siot、mqttx等进行本地搭建,也可以使用easyiot,或者中国...
是一个节点式编程的在线平台,也就是配置好环境之后,在本地服务器使用浏览器进入编程后台来控制软硬件。如果是像树莓派一样具有GPIO引脚的微型计算机,可以通过nodered后台直接操控其GPIO引脚来读取传感器信息和下发控制指令。如果是个人pc,也可以通过nodered的serialport节点库来跟单片机进行串口通信,或者自带的mqtt节点来...

在物联网环境下,WebSocket 可用于实时数据通过将 WebSocket 与 ESP32、Node-RED 和 InfluxDB 结合使用,可以创建实时数据流和可视化系统。ESP32 可以编程为使用 WebSocket 协议将数据发送到服务器,然后可以使用 Node-RED 处理数据并将其存储在 InfluxDB 中。然后可以使用 InfluxDB 强大的数据可视化工具实时可视化数据。

The path of the binary firmware image is based on the project name, platform/subplatform, and build type. For a release build of node-red-mcu for Moddable Two (esp32/moddable_two), the firmware image is at$MODDABLE/build/bin/esp32/moddable_two/release/node-red-mcu/xs_esp32.bin. ...
This initial effort successfully runs useful, if small, Node-RED projects on MCUs. They run reliably and perform well. They have been tested on ESP32 and ESP8266 MCUs. The ESP8266 is quite constrained, running at 80 MHz with only about 45 KB of RAM. Both are able to run flows that ...
