As a result of my researches i have found my pulse-rate sensor that can measure pulse-rate. It is an optical heart-rate sensor. Which reflects a light onto a fingertip and it measures the time that the light bounces back from the finger. It is a very simple understanding of a pulse-rate. Here is the explanation of the working system of the sensor.
“Optical heart-rate monitors are easy to understand in theory. If you’ve ever shined a flashlight through your finger tips and seen your heart-beat pulse (a thing most kids have done) you have a good handle on the theory of optical heart-rate pulse sensors.
In an optical heart-rate pulse sensor, light is shot into a finger tip or ear lobe. The light either bounces back to a light sensor, or gets absorbed by blood cells. As you continue to shine light (into say a fingertip) and take light sensor readings, you quickly start to get a heart-beat pulse reading. The theory is easy to understand. In practice, it hard to master DIY optical heart-rate sensors, or get them operational at all. There are many tutorials online and in publications describing how to make DIY heart-rate sensors.”
Pulse Sensor Amped is a greatly improved version of our original Pulse Sensor, a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.
Pulse Sensor Amped added amplification and noise cancellation circuitry to the hardware. It’s noticeably faster and easier to get reliable pulse readings. Pulse Sensor Amped works with either a 3Volt and 5Volt Arduino. We’ve discontinued our previous Pulse Sensor models, because this one is far better.
Lastly, we’ve also streamlined and improved theProcessing visualization software and Arduino code that comes with this hardware.
The kit includes:
1) A 24-inch Color-Coded Cable, with a standard male header connectors. Plug it straight into an Arduino or a Breadboard. No soldering is required.
2) An Ear Clip, perfectly sized to the sensor. We searched many many places to find just the right clip. It can be hot-glued or epoxied to the back of the sensor to get reading from an ear lobe.
3) Parts to make a handy Velcro Finger Strap. This is another great way to get heart-rate data.
4) 4 Transparent Stickers, to insulate the front of the Pulse Sensor from oily fingers and sweaty earlobes.
5) The Pulse Sensor has 3 holes around the outside edge which make it easy to sew it into almost anything.
6) Visualization software (made in Processing) to instantly see output of the sensor and for troubleshooting.
