Solar IoT Monitoring Platform
Real-time solar charger monitoring platform for connected devices and energy data using Raspberry Pi and MQTT.
Problem
Needed real-time monitoring of distributed solar charger devices across multiple locations with no reliable internet connectivity.
Solution
Built an end-to-end IoT platform with Raspberry Pi edge devices communicating via MQTT to a centralized Node.js backend, with a React dashboard for live data visualization — including live energy flow, a device map, and CO₂ offset/carbon credit tracking.
Architecture
Device → Raspberry Pi → MQTT Broker → Node.js Backend → MySQL → React Dashboard
My Contribution
Designed the full system architecture, developed the MQTT integration layer, built the real-time dashboard and device map, and deployed on Linux VPS with Nginx and PM2.
Result
Currently monitoring 510 devices (338 online) across Rajasthan in real time, with a 66.3% success rate and live tracking of solar output, CO₂ offset, and carbon credits.
