KY-039 Finger Detection Heartbeat Measuring Sensor Module

Finger Detection Heartbeat Measuring Sensor Module uses a bright infrared LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse. This component is ideally suited to adding heartbeat sensing to your project.

The most important is to keep the shield stray light into the phototransistor. For home lighting that is particularly important because the lights at home mostly based on 50HZ or 60HZ fluctuate, so a faint heartbeat will add considerable noise.

As a simple module, it will suit use within a large range of projects based on microcontrollers such as Arduino boards and the Raspberry Pi. The module has an M2 mounting hole allowing for its easy attachment to a multitude of surfaces

Features :

• Easy to use
