Syllabus & Module Progression

  1. Choose a useful measurement
    25 minsMeasurement & Sensor Design

    Select sensors, establish sampling frequency, define calibration reference, and avoid noise.

  2. Design for connection loss
    35 minsNetwork Resilience & Queuing

    Design offline FIFO telemetry queues, prevent duplicate readings, and manage token credentials.

Includes a comprehensive final knowledge check to validate conceptual mastery.
