KY-039 Finger Detection Heartbeat Measuring Sensor Module

Description

1. Heartbeat Detection: The module is equipped with a photodetector and an LED. It measures changes in light absorption caused by blood flow in the fingertip to detect heartbeats.
2. Analog Output: The KY-039 module typically provides an analog output signal that varies in response to the heartbeat and pulse rate. The analog signal represents the changes in blood flow.
3. Compatible with Arduino: This module can be easily integrated with Arduino and other microcontroller platforms. Libraries and example code are often available for interfacing with the sensor.
4. Compact Design: The module is compact and can be easily attached to a fingertip or integrated into wearable devices.
5. Low Power Consumption: It is designed to be energy-efficient, making it suitable for battery-powered health monitoring applications.
