LabVIEW Smart Fetal ECG
Budget: ₹600 – ₹1,500 INR
I need a LabVIEW solution that turns my fetal ECG sensor into a smart, clinician-friendly tool. The VI must deliver real-time monitoring with both visual readouts and a continuous graphical waveform while simultaneously recording every sample to a CSV file.
Real-time monitoring
• Display a scrolling ECG trace and numeric indicators (heart rate, signal amplitude).
• End-to-end latency below 250 ms so the waveform feels live.
Data recording & storage
• Write directly to CSV, one line per sample with ISO-timestamp, channel values, and derived metrics.
• Start a new file automatically every 30 minutes or at 50 MB to keep files manageable.
Code design
Keep hardware I/O in a dedicated sub-VI so I can swap between NI-DAQ, myRIO, or a simple serial interface without touching your core logic. Document the block diagram clearly and label every control and indicator on the front panel.
Acceptance criteria
• Continuous run for ≥2 hours without memory leaks or missed samples.
• CSV opens cleanly in Excel, no gaps or duplicate timestamps.
• Front panel groups and labels are intuitive for clinical staff.
If you already have biomedical signal-conditioning code or experience extracting fetal ECG, that’s a bonus. Clean, well-commented LabVIEW code and a short README are the only deliverables I need to sign off.
