Describe what your project does?: This project is a 6-node AI agent built with LangGraph that automates IoT maintenance. It processes real-time sensor streams using a hybrid approach: first applying four statistical methods (Z-Score, IQR, Trend, Rate-of-Change) to filter noise, then triggering GPT-4 to analyze confirmed anomalies for root cause diagnosis. Why it matters: Traditional monitoring only flags that something is wrong; this agent explains why it’s wrong and how to fix it. It eliminates false positives and empowers engineers with actionable, autonomous insights rather than raw data alerts.
