GroundGuardian:Intelligent Earthing Health Monitoring System

Smart IoT-based monitoring of earthing systems that detects leakage, continuity failures, and high earth resistance while providing instant alerts.

Inspiration

Electrical pole lights, public lighting systems, railway stations, and smart city infrastructure depend on proper earthing for public safety. Traditional earthing inspections require manual testing and large manpower, making fault detection slow and inefficient. We were inspired to develop a Smart Earthing Monitoring System that continuously monitors earthing health, detects faults in real time, and alerts maintenance personnel before hazardous situations occur.

What it does

The GroundGuardian:Intelligent Earthing Health Monitoring System continuously monitors:

  • Earth leakage current
  • Earthing continuity
  • Earth pit resistance
  • System health status

The system uses sensors connected to an ESP32 microcontroller to collect real-time data. Whenever abnormal conditions such as excessive leakage current, broken earthing continuity, or increased earth resistance are detected, the system generates instant alerts through visual indicators, audible alarms, and cloud notifications. The collected data is also transmitted to a centralized monitoring dashboard for remote supervision.

How we built it

The system was developed using:

  • ESP32 Microcontroller
  • Current Sensor (ACS712/CT Sensor)
  • Voltage Sensing Circuit
  • Earthing Resistance Measurement Circuit
  • Wi-Fi Communication
  • IoT Cloud Dashboard
  • Embedded C Programming
  • Arduino IDE

The sensors continuously acquire electrical parameters and transmit them to the ESP32. The controller processes the sensor data, compares it with predefined safety thresholds, and uploads the information to the cloud dashboard. Fault conditions trigger immediate alerts for maintenance teams.

Challenges we ran into

  • Designing a reliable method for measuring earth resistance continuously.
  • Ensuring accurate leakage current detection under varying load conditions.
  • Reducing false alarms caused by electrical noise and environmental factors.
  • Integrating multiple sensors into a single monitoring platform.
  • Developing a scalable architecture suitable for large public infrastructures.

Accomplishments that we're proud of

  • Developed a real-time earthing health monitoring prototype.
  • Achieved automatic fault detection without manual inspection.
  • Enabled remote monitoring through IoT connectivity.
  • Reduced dependence on periodic manual testing.
  • Designed a scalable solution suitable for smart cities, railway stations, and public lighting networks.

What we learned

Through this project, we gained practical experience in:

  • Embedded system design
  • IoT-based monitoring systems
  • Sensor integration and calibration
  • ESP32 programming
  • Real-time fault detection
  • Cloud data visualization
  • Electrical safety and grounding systems

We also learned how predictive monitoring can significantly improve public safety and reduce maintenance costs.

What's next for GroundGuardian:Intelligent Earthing Health Monitoring System

Future enhancements include:

  • AI-based fault prediction and maintenance scheduling.
  • Mobile application for maintenance teams.
  • GIS-based fault location mapping.
  • Integration with Smart City control centers.
  • LoRaWAN and NB-IoT communication support for long-range deployment.
  • Advanced analytics and historical trend monitoring.

Our long-term vision is to create a fully autonomous earthing management platform capable of ensuring electrical safety across large-scale public infrastructure.
