⚡ Project Story: WattsUp 📌 About the Project WattsUp is a smart energy monitoring system designed to give users real-time insight into their electricity consumption. With rising energy costs and increasing concern over environmental sustainability, we saw a need for a solution that empowers individuals and institutions to better understand and optimize their power usage.

🌱 What Inspired Us The idea was born in our student hostel, where high electricity bills were common, but no one really knew why. We realized that a lot of power was being wasted without our knowledge—devices left on, inefficient appliances, and no awareness of peak usage times. This inspired us to build a system that could bring visibility and control to everyday energy consumption.

🛠️ How We Built It Hardware: We used an ESP32 microcontroller paired with current and voltage sensors to gather live electrical data.

Backend: Data is sent to a cloud database (Firebase) for storage and analysis.

Frontend: A React-based dashboard visualizes real-time and historical consumption, with charts built using Recharts.

Extras: We included features like anomaly detection, device-level insights, and energy-saving recommendations.

🚧 Challenges We Faced Calibrating the sensors accurately to get reliable readings

Ensuring real-time data transfer without loss or lag

Designing a clean and responsive UI that works across devices

Managing power supply and safety in hardware setup

🎓 What We Learned IoT system integration and sensor interfacing

Real-time data visualization and frontend/backend communication

User-centered dashboard design

The impact of small behavior changes on energy savings

WattsUp isn’t just a project—it’s a step toward more sustainable, informed living
