IR Pulse (Heart Rate) Sensor Module To247-3 Type Male Box header Pitch

Type Male Box header Pitch 2

2 ohm Color Code Black

Brass is the base material with gold plating

the resistance between the external pins and the centre pin fluctuates from 0 to 500K ohm as the potentiometer rotates

The resistance between the outer two pins is always 20K

IR Pulse (Heart Rate) Sensor Module To247-3 Type Male Box header PitchThis component is ideally suited for 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 M2
