The pulse sensor detects the heartbeats and converts them into Analog voltage values. The Arduino reads these Analog values through the Analog input pin. The getBPM function can be customized based on ...

This project presents a real-time stress detection system using a PPG (Photoplethysmogram) sensor and Arduino UNO R4. The sensor captures pulse data, which is transmitted to a Python program where ...

The Geek Pub guide will help get you started with an Arduino pulse sensor. While sensors like this are reliable, it's worth keeping in mind that your heart rate can tell you a lot of different things.
