Streaming Accelerometer Readings to a Real-time Dashboard

In this blog post, the author details a project that involves connecting a SainSmart ADXL335 Triple Axis Accelerometer to the Internet using an Intel Galileo, and streaming its data in real time to a dashboard. The accelerometer, a small sensor capable of measuring static and dynamic acceleration, is integrated with the Intel Galileo—an IoT prototyping chip running NodeJS—through soldering and wiring. The data from the accelerometer is then published via PubNub, a real-time network service, allowing it to be streamed and visualized on a live-updating HTML dashboard using the EON chart framework. The process includes setting up PubNub as a dependency in Node.js, reading the accelerometer's X, Y, and Z axis data, and rendering this information in a bar chart format on the dashboard. The blog concludes by suggesting potential extensions to the demo, such as incorporating additional sensors or microcontrollers to enhance functionality.
