Arduino Power Monitor
https://github.com/sainisahil1/arduino-power-monitor- Designed and implemented a complete IoT system using Arduino, MQTT, Spring Boot, and React.js to monitor energy consumption of connected devices.
- Developed Arduino firmware in C++ to collect real-time current readings and transmit data via MQTT protocol using EMQX broker.
- Built a Spring Boot backend that subscribes to MQTT topics for real-time data ingestion, processes device analytics, and stores time-series data in InfluxDB.
- Chose InfluxDB for its performance with time-based data, leveraging features like downsampling, retention policies, and inverse indexing for historical querying.
- Enabled real-time and historical visualization through a web dashboard (React.js) and a mobile app, both subscribing to the same MQTT topics.
- Implemented daily, weekly, and monthly consumption analysis, with backend APIs providing statistical summaries.
- Designed the system to support scalability and low latency, ensuring smooth real-time updates across all clients.
- Focused on modular architecture with clear separation between device, broker, backend processing, and client interfaces.
