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 an M2 mounting hole allowing for its easy
attachment to a multitude of surfaces.
