Smart Digital Energy Meter with Voltage and Current Monitoring using Arduino

The Smart Digital Energy Meter is an advanced system designed to measure and monitor voltage, current, and power consumption using an Arduino microcontroller. This project enhances traditional energy meters by providing real-time data display and remote monitoring capabilities, making it ideal for homes, industries, and smart energy management systems.

How It Works

1. Voltage & Current Measurement:
   • A current sensor (ACS712) and a voltage sensor are used to measure power consumption.
   • Arduino processes the sensor data and calculates power (Watt) and energy (kWh).
2. Digital Display & Alerts:
   • Data is displayed on an LCD screen or OLED display for real-time monitoring.
   • Alerts can be triggered for overvoltage, undervoltage, or excessive power usage.
3. Wireless Monitoring (Optional):
   • Can integrate GSM, WiFi, or IoT modules to send data to a mobile app or cloud dashboard.
   • Users can track energy consumption remotely.
