Description
The KY-039 Finger Heartbeat Detection Sensor Module is a simple and low-cost pulse sensor used to detect heartbeats by measuring changes in blood flow through a fingertip. It works on the principle of photoplethysmography (PPG) using an infrared LED and phototransistor.
This module is widely used in Arduino, ESP8266, ESP32, and Raspberry Pi projects for learning, experimentation, and basic heart rate monitoring. It provides an analog output signal that can be processed using software to calculate heart rate (BPM).
The KY-039 sensor is ideal for students, hobbyists, and DIY electronics enthusiasts exploring biomedical and health-related projects.
