Node.js IoT: Logging Data That Is Out of This World

[Dave Johnson]

In this tutorial, I explore how to log data in IoT applications using Node.js, focusing on creating a simple logging system to track the distance from the International Space Station (ISS). By utilizing built-in Node modules and a few external libraries, I demonstrate how to log this data to a CSV file, allowing for easy analysis in spreadsheet software. The tutorial covers setting up a logging directory, implementing conditional logging to track the closest and furthest distances from the ISS, and highlights the importance of logging for future data analysis, whether the sensor is in space or on a desk.
