"Smart Overload Protection System with Automatic Power Cutoff"



This project is an Automatic Overload Protection System that monitors current consumption in an electrical circuit and automatically disconnects the load if an overload is detected. It uses an ACS712 current sensor to measure real-time current, an Arduino Uno for processing, and a relay module to switch the power supply. An LCD display shows the current reading and system status.
Features:
✅ Real-time Current Monitoring – Measures AC/DC current using an ACS712 sensor
✅ LCD Display (I2C) – Displays current in Amps and status (Safe, Moderate, Overload)
✅ Automatic Relay Cutoff – Turns OFF the system if overload is detected
✅ No Auto-Restart – The system remains OFF until manually reset
✅ Handles Different Loads – Works with LED bulbs & high-power filament bulbs
Applications:
🔸 Home Automation – Prevents electrical overload & short circuits
🔸 Industrial Safety – Protects equipment from overcurrent damage
🔸 Smart Energy Management – Monitors power consumption in real-time
🔸 IoT-based Energy Monitoring – Can be extended with wireless monitoring
Components used:
- 🔹 Arduino Uno
🔹 ACS712 (5A) Current Sensor
🔹 Relay Module (Active Low)
🔹 16x2 LCD Display (I2C)
🔹 LED Bulbs & Filament Bulb
🔹 Power Supply & Connecting Wires
