Grid Frequency & Voltage Monitoring System
Monitor grid frequency and voltage quality in real-time using Arduino. Detect anomalies. Alert on violations of standards. Create grid quality report.
Safety: Involves mains/AC or high-current power. Work only under instructor supervision, use proper isolation, fusing, and PPE. Prefer low-voltage or simulated sources where possible.

Steps
- Review AC safety and use an isolated, enclosed voltage sensor with instructor supervision.
- Wire the ZMPT101B sensor, frequency meter, SD card module, and LCD to the Arduino.
- Program the Arduino to calculate RMS voltage and frequency and log them every second.
- Set alert thresholds based on standard voltage and frequency limits.
- Log data for several days and flag every event outside the limits.
- Create a grid quality report and document the project for your portfolio.
