Build and Deploy a Retail Store Items Detection System using Node-RED on IoT Edge device

Node-RED is a low-code programming language for event driven applications. It is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click. JavaScript functions can be created within the editor using a rich text editor. It comes with a built-in library that allows you to save useful functions, templates or flows for re-use.
