Theory–Practical Distribution
Out of the 1.5 hours of daily class time, only the first 25 to 30 minutes are dedicated to theory. The rest is spent on labs, debugging, and project work — because IoT engineering is muscle memory, not memorisation.
| Component | Daily Time | Activity Examples |
|---|---|---|
| Theory (30%) | ≈ 27 minutes | Concepts, protocols, architectures, security primitives, design principles |
| Practical (70%) | ≈ 63 minutes | Labs, coding, hardware interfacing, debugging, projects, demos |
Assessment Structure
| Component | Weightage | Description |
|---|---|---|
| Practical Lab Assessment | 30% | Daily lab logbook quality, dashboard work, sensor-to-cloud chains. |
| Capstone Project Evaluation | 30% | Working multi-node prototype, dashboard, mobile element, demo. |
| Viva-Voce | 15% | Theory on MQTT, WiFi, LoRa, cloud platforms and IoT security. |
| Assignments & Quizzes | 10% | Concept checks, JSON design tasks, cloud-account assignments. |
| Attendance & Participation | 10% | Engagement, peer support, classroom presence. |
| Innovation Score | 5% | Originality — cloud rules, security features, energy optimisations. |
