Item specifics


Brand Name: Finger heartbeat detection module

Model Number: Finger heartbeat detection




Item Description

This project uses bright infrared (IR) LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse.
Pulse monitor works as follows: The LED is the ght side of the finger, and phototransistor on the other side of the finger, phototransistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the phototransistor will be sght changed.

We chose a very high resistance resistor R1, because most of the ght through the finger is absorbed,it is desirable phototransistor sensitive enough.Resistance can be selected by experiment to get the best results.
The most important is to keep the shield stray ght into the phototransistor. For home ghting that is particularly important because the ghts at home mostly based 50HZ or 60HZ fluctuate, so faint heartbeat will add considerable noise.   Package Including: 1pcs Finger Measuring Heartbeat Sensor Module for Arduin
