Overview
A comprehensive full-stack IoT platform for real-time sensor monitoring. Features a React frontend with live data visualization, Python backend with MQTT integration, and PostgreSQL for time-series data storage. Includes alerting, historical analysis, and multi-tenant support.
The Challenge
Building a scalable platform that could handle thousands of sensors publishing data simultaneously while providing sub-second visualization updates. The system needed to support historical queries spanning months of data without impacting real-time performance.
The Solution
Implemented a microservices architecture with MQTT broker for ingestion, Python workers for processing, TimescaleDB for efficient time-series storage, and Redis for caching recent data. The React frontend uses WebSockets for real-time updates and implements virtualized lists for handling large datasets.
