IR Pulse (Heart Rate) Sensor Module To247-3 causing the gauge to deform

causing the gauge to deform as well

The resistance between the outer two pins is always 20K

Easy to use with Microcontrollers

It can drive any load that is less than 150 mA

it is very important to remember that a Zener diode should always be used along with a Zener resistor

IR Pulse (Heart Rate) Sensor Module To247-3 causing the gauge to deformThis 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
