KY039 Finger Detection Heartbeat Measuring Sensor Module النكيه ATMEGA328P is most popular ofIntroduction: Finger Detection Heartbeat Measuring Sensor Module KY 039 uses bright infrared (IR) 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. Pulse monitor works as follows: The LED is the light side of the finger, and phototransistor on the other side of the finger, photo transistor used to obtain the flux emitted, when
