VacuumSens

Overview

Real-time sensing platform that streams embedded data through WebSockets into a React analytics dashboard with persistent MongoDB storage.

Challenge

Build a dependable end-to-end system that can capture sensor readings, move data with low latency, and make results immediately usable for monitoring and analysis.

System Design

• Custom sensing hardware captures environmental measurements at configurable intervals.
• A lightweight edge transport layer forwards data over WebSockets for real-time updates.
• Backend ingestion stores time-series data in MongoDB and serves queryable APIs.

Build Details

• Designed stream-safe message formatting for consistent parsing across client and server.
• Developed dashboard views with rapid visual feedback and stateful trend inspection.
• Added baseline validation checks for noisy values before persistence.

Outcomes

• Enabled near-live visibility into sensor behavior from browser clients.
• Created a reusable architecture for future embedded monitoring projects.
