Electrocardiógrafo IoT
An own-design IoT electrocardiograph with signal processing in the browser and identification of P-QRS-T waves.
An electrocardiograph (ECG) built with cheap components: the AD8232 sensor, an Arduino Pro Micro for capture and a Vocore2 Linux board that serves the signal in real time over websockets.
The waveform is drawn in the browser with HTML5 Canvas, and processed right there: a Fourier transform to filter noise and identify the fiducial points of the P, Q, R, S and T waves. The project also explores its cybersecurity uses, such as biometric identification.
Presented as «Seguridad Social DIY» at RootedCON 2022 and as «IoT electrocardiograph for healthcare dystopias» at Navaja Negra X.
