Sometimes, a project comes along that makes a good reference design for anyone doing similar work. In this particular case, it’s a DIY USB polygraph-like machine by [Juangg] using an Arduino and ...

The new e-Health sensor platform adds sensing capability for nine different biometric parameters, such as pulse, blood pressure, oxygen in blood (SPO2), electrocardiogram (EKG), airflow ...

This project builds a real-time stress detection system using a PPG sensor and Arduino UNO R4. Pulse data is processed in Python to extract features and predict stress with a Random Forest model.
