ESP32 Vitals Monitor

An ESP32 reading heart rate, SpO2, body temperature, and a single-lead ECG, serving its own live dashboard over WiFi from a self-hosted access point; no router, app, or internet connection needed.

• A self-contained vitals monitor: heart rate, SpO2, body temperature, and a single-lead ECG all read from one ESP32
• Serves its own live dashboard straight from the board over WiFi, no router, app, or internet connection needed
• Plots a live, adjustable ECG waveform on the dashboard, not just a single heart-rate number
• Timestamps every ECG sample as it arrives in the browser, so the trace stays accurate even if the WiFi send rate drifts
