Opensource Optical Heart Rate Sensor/Pulse Sensor for Arduino

In this episode, we are showcasing the Optical Heart Rate Sensor (SEN0203) and comparing PPG (Photoplethysmography) with ECG (Electrocardiography) technology as two general ways of measuring heart rate with Arduino, Raspberry Pi, and other microcontrollers.
The Optical Heart Rate Sensor (SEN0203) 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.
For easier use, a Gravity Interface is adapted to allow plug&play. The IO sensor shield is the best match for this sensor connecting to your Arduino or other microcontrollers. The sensor is able to work at 3.3V which makes it compatible with Raspberry Pi, Intel Edison, Joule, and Curie.
Input Voltage (Vin): 3.3 - 6V (5V recommended)
Output Voltage: 0 - Vin (Analog), 0/ Vin (Digital)
Operating current: no more than 10mA
Dimension: 28 x 24(mm), 1.102" x 0.945"(in)
Interface Type: PH2.0-3P

Thanks for this video

[@nickmikkelsen817]

Really good video thank you.

Great video. Hopefully DFRobot will develop an open source optical heart rate sensor, which is as accurate as the Polar OH1. We immediately would deside for this product. Polar changes the running time of the Polar OH1 by only a firmware update. There where validation papers for the Polar OH1 with g.Nautilus ECG devices for more than 50 000 USD. This makes the validation of the sensor useless. Therefore we are looking for an open source heart rate sensor. Develop a more accurate PPG sensor, DFRobot, and we immediately will buy from you. Greetings, Peter Gamma, Physiologist & Director, Meditation Research Institute Switzerland (MRIS).

This was a great video!! Is there a sensor you would recommend for measuring pulse at the bicep or upper arm? The light from the fingertip pulse sensor may not penetrate deep enough and the device I am working on can only be attached to the upper arm or thigh. I know it's a long shot, but I figured I'd ask. Thanks for the video and have a great day!

What are the axes of analogue and digital results (Y for and X for)?

[@diao77723]

Hey, Im looking to make this, but how can I make it self contained, i want it to be self sucificient and not relying on a laptop or PC for starting the reading, how can I auto export the data to a screen included.
Basically how can I activate the serial plotter without using a PC ?

You may use something else that supports serial communication. Or simply connect an LCD screen to the Arduino.

[@imansarah8008]

Can this device be connected to processing?

[@DFROBOTCN]

Yes, you can connect Arduino to Processing through serial and display the outputs in Processing.

[@user-zq4vx4qu5h]

Yes
