๐ Topic Summary
Unplugged data collection with sensors is a way to understand how sensors work and how data is gathered without relying on computers. Instead, we use everyday objects and simple activities to mimic what sensors do โ detect changes in the environment (like temperature or light) and record that information manually. This helps build a foundational understanding of data and sensor technology before introducing complex computer systems.
Think of it like this: You use your hand to feel the temperature of a cup of water. That's your hand acting like a temperature sensor! You then record whether it's hot, cold, or lukewarm. That's data collection! By doing this without a computer, you're focusing on the core concepts of sensing and data analysis.
