  1. Foundations: IoT Protocols & Embedded Basics

    4 weeks
    Goals
    • Understand MQTT, CoAP, and HTTP-based IoT communication patterns
    • Set up a Raspberry Pi or ESP32 with sensors publishing to a local MQTT broker
    • Learn basic Python and C for reading sensor data and controlling actuators
    Resources
    • MQTT Essentials (HiveMQ blog series)
    • AWS IoT Core Getting Started tutorials
    • Raspberry Pi official documentation
    • Coursera: Introduction to IoT and Embedded Systems (UC Irvine)
    Milestone

    You can wire up a multi-sensor device publishing telemetry to an MQTT broker and visualize it in Grafana.

  2. AI Fundamentals: LLMs, Agents & Tool Use

    6 weeks
    Goals
    • Master prompt engineering, function calling, and structured output with OpenAI/Anthropic APIs
    • Build a basic LangChain agent with custom tools that call external REST APIs
    • Understand RAG architecture: embeddings, vector stores, retrieval, and context injection
    Resources
    • LangChain documentation and quickstart guides
    • OpenAI function calling and Assistants API docs
    • DeepLearning.AI short courses on LangChain and AI Agents
    • Hugging Face NLP course (first 5 chapters)
    Milestone

    You can build an LLM agent that plans multi-step actions, calls external APIs, and answers questions from a document store.

  3. IoT-AI Integration: Building Agent-Device Pipelines

    6 weeks
    Goals
    • Design an agent orchestration graph (LangGraph) that consumes MQTT events and decides actions
    • Implement tool-calling schemas for device control APIs (read sensor, set threshold, trigger actuator)
    • Build a message bridge service (Python + paho-mqtt) that translates device events into agent prompts
    Resources
    • LangGraph documentation and tutorial notebooks
    • paho-mqtt Python client library
    • AWS IoT Core Device Shadow documentation
    • Real-world case studies: smart building, precision agriculture
    Milestone

    You can deploy an agent that subscribes to sensor MQTT topics, reasons about anomalies via an LLM, and issues corrective commands to devices.

  4. Edge Deployment & Safety Engineering

    6 weeks
    Goals
    • Deploy lightweight models (ONNX, TFLite) on Jetson Nano or Edge TPU for local inference
    • Implement safety interlocks and human-in-the-loop approval for critical actuation
    • Build agent observability dashboards: reasoning traces, tool-call latency, error rates
    Resources
    • NVIDIA Jetson inference tutorials
    • ONNX Runtime documentation for edge devices
    • LangSmith agent tracing platform
    • IEC 61508 / ISO 13849 overview for functional safety concepts
    Milestone

    You can deploy a production-grade agent system with edge inference, safety guardrails, and full observability across the agent-device pipeline.

  5. Capstone: Full-Stack IoT Agent System

    6 weeks
    Goals
    • Architect and deliver an end-to-end IoT agent system for a realistic use case (e.g., predictive maintenance, environmental monitoring, smart energy)
    • Implement RAG over device documentation and maintenance history for contextual agent reasoning
    • Present a portfolio-ready project with architecture diagrams, demo video, and benchmark results
    Resources
    • Domain-specific IoT datasets (UCI ML Repository, Kaggle)
    • AWS IoT + Lambda + DynamoDB architecture references
    • Technical blog writing guides for portfolio presentation
    • Peer review via online communities (Reddit r/LocalLLaMA, MLOps Community)
    Milestone

    You have a complete, demonstrable IoT agent system and the portfolio evidence to pursue AI IoT Agent Engineer roles.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Smart Greenhouse Agent

Beginner

Build an LLM-powered agent that monitors temperature, humidity, and soil moisture sensors via MQTT and autonomously adjusts fans, lights, and irrigation pumps through relay-controlled actuators. The agent reasons about sensor thresholds and weather forecasts.

~25h
MQTT communicationLLM tool-calling basicsSensor data handling

Predictive Maintenance Chatbot for Industrial Motors

Intermediate

Create a RAG-powered agent that ingests vibration and temperature data from industrial motor sensors, indexes maintenance manuals and historical fault logs into a vector store, and allows operators to ask natural-language questions about equipment health and receive actionable maintenance recommendations.

RAG pipeline designTime-series data summarizationHugging Face embeddings

Multi-Zone Smart Building Energy Optimizer

Intermediate

Deploy an agent system that reads occupancy, temperature, and energy consumption data from 10+ zones, uses a foundation model to optimize HVAC and lighting schedules, and invokes building management system APIs to adjust setpoints. Includes a Grafana dashboard for monitoring agent decisions.

~50h
Multi-device orchestrationStream processingAgent observability

Fleet Drone Mission Coordinator with Contingency Planning

Advanced

Build a multi-agent system where a supervisor agent coordinates delivery drone missions, delegates to per-drone agents, and handles contingencies (GPS loss, low battery, weather changes) by replanning routes and invoking return-to-base commands. Tested with a drone flight simulator.

Multi-agent architectureLangGraph conditional routingSafety interlocks

Air-Gapped Factory Agent with Edge LLM

Advanced

Deploy a fully self-contained IoT agent system on NVIDIA Jetson devices in a factory with no internet access. Uses a locally-hosted fine-tuned Llama model, local vector store, Modbus-to-MQTT bridge, and K3s orchestration. The agent monitors CNC machine health and generates maintenance tickets locally.
