IntroductionNode-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based 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. It is build on Node.js. Node Red can be installed on Raspberry Pi and its server can be run on it. A sensor is connected to Raspberry Pi and this data is sent to mobile as a SMS. The whole thing is done using Node Red. The ultrasonic sensor is connected to Raspberry Pi and coding done using Python. Node Red has a inbuilt nodes installed in it. Using the exec node in Node Red it takes the data from ultrasonic sensor. This data is send to mobile using Twilio node in the Node Red. Let’s do this in step by step.”
