Pulse Rate & Heartbeat Sensor Module for Arduino & Raspberry Pi | Optical Detection

The Pulse Rate Sensor Module is a compact, easy-to-use optical sensor designed to detect and monitor human heartbeat and pulse rate. Using a photoplethysmography (PPG) technique, it detects minute changes in blood flow through a fingertip or earlobe and outputs an analog signal, which can be read by Arduino, Raspberry Pi, or any compatible microcontroller.

Perfect for health monitoring systems, wearable tech, fitness trackers, and biofeedback applications, this module enables real-time measurement of cardiovascular data in DIY and professional projects.

With simple wiring and high sensitivity, it’s ideal for students, hobbyists, and developers working on biomedical or IoT-based health tech.
