Streaming Sensor Readings to a Real-time Gauge Chart

The blog post outlines the process of creating a real-time IoT dashboard that streams pressure data from a sensor connected to an Arduino board, using the EON JavaScript framework to visualize the data as a gauge chart. It details the setup of a server-side application using Node.js and npm packages such as PubNub and Johnny-Five to publish the sensor readings to a PubNub channel, and a client-side HTML application to display the gauge chart using EON's visualization capabilities. The tutorial emphasizes the scalability and flexibility of EON, which works with various boards and sensor modules, offering different types of charts for robust real-time visualizations, and provides guidance on setting up and running the program, including a live demonstration video.
