Heart Rate Pulse Sensor Module for Arduino is a biometric sensing device designed to measure heart rate using photoplethysmography (PPG) technology. The sensor uses an LED and a photodetector to sense changes in blood volume caused by heartbeats, converting them into electrical signals.
The module provides an analog output signal that can be read by Arduino, ESP32, ESP8266, and other microcontrollers for real-time heart rate monitoring. It is designed for easy finger or earlobe placement, ensuring stable and accurate pulse detection when used correctly.
This pulse sensor is widely used in health monitoring systems, fitness trackers, wearable electronics, medical demonstration projects, and educational biomedical experiments. Its small size, low power consumption, and ease of integration make it suitable for students, hobbyists, researchers, and developers working on health-related electronics projects.
