Project Overlook
This project develops a real-time data acquisition system for monitoring key parameters of a single-phase AC electrical power system using Arduino-based hardware and the Blynk mobile application.
This project develops a real-time data acquisition system for monitoring key parameters of a single-phase AC electrical power system using Arduino-based hardware and the Blynk mobile application. The system measures and displays electrical parameters like voltage, current, power, and power factor, providing users with real-time data through a mobile app. This prototype aims to support smart grid development by offering accurate monitoring and data logging.
Objectives
- To develop a system for real-time acquisition of electrical parameters such as voltage, current, power, and power factor.
- To transfer the data to a Blynk mobile application for easy visualization and monitoring.
- To create a secure communication system between the Arduino controller and the mobile app through a private server.
Methodology
- System Setup:
- Used Arduino Uno with ZMPT101B voltage sensors and ACS712 current sensors for measurement.
- Configured an auto-transformer to provide variable voltage for testing under different conditions.
- Data Processing and Accuracy:
- Implemented the “emon” library to calculate power factor by measuring the time difference between voltage and current signals.
- Real-time data was sent to a private server and displayed on the Blynk app, offering both numerical and graphical representations.
- Security and Communication:
- Communication between the hardware and mobile app was secured with an authentication code, ensuring data integrity.
Results and Discussion
- The system successfully measured and transmitted real-time data for various test conditions with minimal deviation compared to standard measurement devices.
- The Blynk mobile app provided an intuitive interface for viewing and analyzing data, demonstrating the feasibility of remote monitoring for smart grid applications.
- Voltage and current readings in the app closely matched values obtained from standard meters, validating the system’s accuracy.
Conclusion
The project demonstrates the effectiveness of real-time data acquisition and monitoring using low-cost hardware and a mobile application. The system can be further expanded to include control actions based on the monitored values, making it a practical solution for smart grid applications and energy management systems.
Future Scope
- Integration with IoT platforms for predictive analysis and enhanced data storage.
- Implementation of control mechanisms to adjust system performance based on real-time data.
- Scaling the system for three-phase power systems and advanced load monitoring.
