Product Description
The Heart Rate Pulse Sensor Module is an optical sensor board designed to measure pulse rate by detecting changes in blood volume as blood flows through peripheral capillaries. It typically uses an IR LED and a photodiode to sense the pulse waveform and outputs an analog signal that can be read by microcontroller ADC pins. This module is widely used in wearable health devices, fitness trackers, biofeedback applications, and embedded systems where heart rate monitoring is needed.
Compatible with Arduino, ESP32, STM32, and Raspberry Pi platforms, the pulse sensor provides an easy way to capture heartbeat data and integrate heart rate monitoring into a wide range of projects.
