System Design - Real-time Sensor System (End-to-End)

Problem Overview

Design a real-time sensor system end-to-end. Starting from sensor selection and use case definition, incorporate PM requirements, then reason through algorithm selection, ML model design, data sourcing strategy, system efficiency, and power consumption. The problem is heavily domain-specific — it is scoped to the…
