Finger Measuring Heartbeat Sensor Module
This component is ideally suited to adding heartbeat sensing to your project. This module 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 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 phototransistor will be slight changed. 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.
This component 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. 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 a M2 mounting hole allowing for its easy attachment to a multitude of surfaces. Pin Description S Analog output 3 to 5V DC Input – Ground.
