"Advanced Energy Monitoring System with Threshold Notifications & Billing Feature"

This project is an Arduino-based system for monitoring electrical parameters, designed to promote safety and energy awareness. It uses a PZEM-004T sensor to measure real-time voltage, current, and energy consumption, which is displayed on an LCD screen.

The system features two key alert mechanisms:

> Overload Alert: It warns the user with an on-screen message if power consumption exceeds a safe limit.

> GSM Notifications: A connected SIM800A module automatically sends an SMS when energy consumption reaches a set threshold and makes a phone call for a higher, critical threshold.

The system also includes a button to easily reset the energy counter, making it a versatile tool for tracking energy usage and remotely managing safety alerts in a home or office environment.
