Description
The Pulse Sensor – Heart Rate Detector is a plug-and-play biometric sensor designed to measure heart rate (BPM) by detecting changes in blood flow through the fingertip or earlobe. It works on the principle of photoplethysmography (PPG) using an integrated LED and light sensor.
This module provides an analog output signal that can be easily read by Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontrollers. It is widely used in health monitoring, wearable electronics, fitness trackers, and educational biomedical projects.
The sensor is lightweight, low-power, and ideal for students, hobbyists, and DIY developers.
