INTRODUCTION
The DFRobot heart rate sensor is a thumb-sized heart
rate monitor designed for Arduino microcontrollers.
This sensor is a pulse sensor which is developed based on PPG (PhotoPlethysmoGraphy)
techniques. This is a simple and low-cost optical technique that can be used to
detect blood volume changing in the microvascular bed of tissues. It is relatively
easy to detect the pulsatile component of the cardiac cycle according to this
theory.
The sensor has two holes that you can use to attach to your belt. You can wrap
on your finger, wrist, earlobe or other areas where it has contact with skin.
To ease the difficult of using this sensor, a Gravity Interface is adapted to allow
plug&play. The
IO sensor shield is
the best match for this sound senor connecting to your
Arduino or
other microcontroller. As this sensor can work at 3.3V which make it compatible
with
Raspberry
Pi
, intel
edison
, joule and curie.
NOTE:
1. This product is NOT a professional medical device
and should not be used to diagnose or treat medical conditions.
2. This sensor is designed to work when the user is not moving. If used while
moving it will give inaccurate results.
