4.1 The Context Problem in IoT
Raw sensor data lacks context:
- A temperature reading of 185°F - is this normal or critical?
- Vibration of 12.5 mm/s - what does this mean for the business?
- Pressure drop of 5 PSI - is action needed?
Context provides meaning:
- 185°F in a furnace → Normal
- 185°F in a refrigeration unit → CRITICAL FAILURE
- 185°F in pharmaceutical storage → PRODUCT LOSS IMMINENT
