IR Pulse (Heart Rate) Sensor Module To247-3 the resistance between the external

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

Meanwell's LRS-50 series is a 50W single-output enclosed type power supply with 30mm of low profile design

The resistance between the outer two pins is always 20K

IR Pulse (Heart Rate) Sensor Module To247-3 the resistance between the externalThis 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
