Node Red and its application

Hello People. This article explains you What is Node Red and its application. Node-RED is a programming tool for wiring together hardware devices, APIs and online services. At the core of Node-RED is Node.js, which (as you know) is a JavaScript runtime that has an active community.

Because of its ease of use, node-red is ideally suited for building IOT and Home control dashboards and automations as well as many other applications.

Node-Red IOT and Home Automation

Industrial IOT and home automation applications will generally use one or more of the following protocols.

  • MQTT
  • HTTP

Nodes for these protocols are part of the core nodes.

Node Red and its application

Various platforms

Node-RED can be used on various platforms. That’s because Node-RED itself is a Node.js application. If you have a runtime environment for Node.js, you can run it. It is mostly used on Edge devices, cloud services, and in embedded formats.

The perfect starting point for Node-RED applications is the ADAM-6700 series modules that come complete with Node-RED installed, plus onboard I/O and an extensive built in library to assist with utilising the ADAMs functions. Other functions and sample code can be added from other Node-RED users or by building your own applications and importing them into other projects you may do in the future.

An example of an application using Node-RED could be for a specific signalling arrangement for alarm monitoring. This could include analogue, serial, or ethernet devices all covered in a single unit that provides email and SMS support via a network. It could also include a dashboard on the local network with raw data that the alarms are based on, with logging on board using an SD Card.

A router using Node-RED can provide monitoring of 4G signal reception, alerts for signal loss, network performance and data usage just to name a few. As with modern equipment, Node-RED can provide benefits to make products intuitive to the user’s requirements whether for additional features or just using the dashboard function for service acknowledgement or fault reporting.
