KY-014-039 Finger Heartbeat Sensor

Ky-039 is a Low cost Heart beat Sensing Module. This Heart beat detection module uses bright infrared (ir) led and a photo-transistor to detect the pulse of the finger, a red led flashes with each pulse. Pulse monitor works as follows: the led is Turned ON on one side of the finger, and photo-transistor is on the other side of the finger. The photo-transistor used to obtain the flux emitted, when the blood flows through the finger then the resistance of the photo-transistor will be vary slightly. This module is ideally suited to adding heartbeat sensing to your project. This detection module combines a phototransistor and IR LED, which when a finger is placed between will provide a varying signal. Reading this analog signal you can interpret a change in signal as a heartbeat. Please note this is a sensitive module and will experience noise from household lights and other sources as such minimizing light to the unit will help with obtaining readings.
