119.5 Common Design Patterns
Across all IoT use cases, these patterns emerge consistently:
1. Sensor Fusion for Reliability Every domain combines multiple sensor types to reduce false positives: - Healthcare: Accelerometer + gyroscope + pressure sensors - Agriculture: Soil + weather + satellite imagery - Manufacturing: Vibration + thermal + acoustic + current
2. Edge-Gateway-Cloud Architecture Three-tier deployments match processing to latency needs: - Edge: Ultra-low-power sensing, immediate alerts - Gateway: Local processing, protocol translation - Cloud: ML training, historical analytics, dashboards
3. Privacy-by-Design Successful deployments architect privacy from the start: - Local processing first (reduce cloud exposure) - Data minimization (collect only whatโs needed) - Anonymization (aggregate rather than individual)
4. Integration-First Design IoT value comes from workflow integration: - Healthcare: EHR integration via FHIR APIs - Manufacturing: MES integration for work orders - Smart cities: Open data platforms for innovation
