GSM-Based Overload Detection and Protection System

The GSM-based overload detection and protection system is designed to monitor electrical loads in real time. If an overload condition is detected, the system automatically sends an SMS alert to a registered mobile number and triggers an alarm. Additionally, a relay is activated to cut off the power supply, preventing potential damage to electrical appliances and reducing the risk of fire or electrical hazards.

Working Principle:

• Load Monitoring: A current sensor (ACS712) continuously measures the current flowing through the circuit.

• Overload Detection: If the current exceeds a predefined threshold, the microcontroller (such as Arduino) detects an overload condition.

• Alert Mechanism:

  • An alarm (buzzer) is activated to notify locally.

  • A GSM module (SIM900) sends an SMS to a registered mobile number, informing the user about the overload condition.

• Supply Cut-Off: A relay is used to disconnect the load from the power source, preventing damage to the electrical system.

  • Manual or Automatic Reset: The system can be reset manually or automatically after detecting normal load conditions.

Advantages:

• Prevents Electrical Hazards: Protects appliances and wiring from damage due to excessive current.

• Remote Monitoring: SMS alerts enable real-time monitoring of load conditions from anywhere.

• Automatic Load Disconnection: Reduces the risk of fire and short circuits by cutting off the supply in overload situations.

• Cost-Effective: Uses readily available components, making it affordable and easy to implement.

• Improved Safety: Alerts and automatic shutdown enhance overall electrical safety.
