Heart Rate Pulse Sensor Module
The Heart Rate Pulse Sensor Module is a compact and easy-to-use biometric sensor designed to measure heartbeats in real time. It works by detecting slight changes in blood flow through the fingertip or earlobe using an optical sensing method. This module is widely used in Arduino, ESP32, Raspberry Pi, and other microcontroller-based health monitoring and wearable projects.
The sensor provides analog output signals that can be processed by a microcontroller to calculate heart rate in Beats Per Minute (BPM). Its lightweight design, low power consumption, and simple interfacing make it ideal for students, hobbyists, and IoT developers.
