PowerTrack is a smart energy monitoring device that leverages IoT technology to track and manage electricity consumption. It measures various electrical parameters such as Voltage, Current, Power, and Energy in real time. With PowerTrack, users can analyze energy usage patterns, calculate electricity bills based on dynamic pricing, and optimize their energy consumption for efficiency and cost savings.
Powered by an ATmega328P microcontroller and an ESP32 module for Wi-Fi connectivity, PowerTrack transmits data to a Firebase Database for secure storage and analysis. It integrates with Google Sheets for seamless data visualization, providing users with an intuitive interface to monitor their energy usage from anywhere.
- Real-Time Monitoring: Tracks voltage, current, power, and energy consumption with high accuracy.
- Dynamic Bill Calculation: Computes electricity bills based on time-of-day pricing and usage patterns.
- Data Logging: Stores historical consumption data in Firebase for future analysis.
