Barometer

Real World Example

Imagine trying to determine the mood of a room full of people based on their expressions. Just as you gauge the atmosphere by observing the facial cues and body language of those around you, a barometer measures the "mood" of the atmosphere by detecting changes in air pressure. In both scenarios, subtle changes—whether in expressions or air pressure—provide vital information about what's happening around you, allowing you to anticipate future changes, like a shift in conversation tone or incoming weather patterns.
