Description

- The KY-039 Heartbeat Detector uses a very high resistance resistor R1, because most of the light through the finger is absorbed, it is desirable that the phototransistor is sensitive enough.

- 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 50HZ or 60HZ fluctuate, so faint heartbeat will add considerable noise.Pulse monitor works as follows: -The LED is the light 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 photo transistor will be slightly changed.Recommended Connection: - Sensor pin S connect to Arduino pin Analoog 0 / A0 - Sensor pin + (middle pin) connect to Arduino pin 5+ - Sensor pin – connect to Arduino pin GNDPackage includes - 1 X KY-039 Heartbeat Rate Sensor Module
