Use Cases
Every IoT use case follows the same pattern
sense → transmit → store → decide → act
1. Smart Homes
Use Case Home automation for comfort, security, and energy efficiency.
Example Smart thermostats like Nest adjust temperature based on occupancy and behavior. Smart locks and cameras like Ring stream events and alerts.
Temperature or motion sensed > data sent > rule applied > device reacts.
2. Healthcare
Use Case Remote patient monitoring and early intervention.
Example Wearables such as Fitbit and Apple Watch track vitals and activity and trigger alerts.
Vitals sensed > transmitted > analyzed > alert raised.
3. Industrial IoT (IIoT)
Use Case Predictive maintenance and factory automation.
Example Sensors monitor vibration, temperature, and pressure to predict failures before they occur using platforms like GE Predix.
Machine signals sensed > streamed > modeled > maintenance action triggered.
Similarly Smart Shelves inventory update, Amazon Go, Tesla Cars, Smart meters, Air Quality and so on.
Why IoT Works Across All Fields
- Sensors are cheap
- Networks already exist
- Storage is inexpensive
- Compute and analytics are mature
