- Blynk IoT Platform
- The HW872A current sensor measures the current drawn by the connected load.
- ESP32 processes the sensor readings and calculates:
- Current Consumption
- Power Usage
- Energy Consumption
- Estimated Electricity Bill
- The processed data is sent to the Blynk IoT platform over Wi-Fi.
- Users can monitor electricity usage remotely in real time.
- Real-time energy monitoring
- Smart electricity bill calculation
- Remote IoT dashboard access
- Continuous live data updates
- Efficient energy usage tracking
