Heart rate and body temp are very important, we made this project for health care in the school, you can ask me anything about the project.

Aug 12, 2017

Both of heart rate and body tempare directly related to the soundness of the human cardiovascular system, this was my general idea of creating such project.

short description

This project describes a technique of measuring the heart rate through a fingertip using an arduino nano.

Quick Explanation

While the heart is beating, it is actually pumping blood throughout the body, and that makes the blood volume inside the finger artery to change too. This fluctuation of blood can be detected through an optical sensing mechanism placed around the fingertip. The signal can be amplified further for the microcontroller to count the rate of fluctuation, which is actually the heart rate.

heart rate sensor function

Heart rate is the number of heartbeats per unit of time and is usually expressed in beats per minute (bpm). In adults, a normal heart beats about 60 to 100 times a minute during resting condition. The resting heart rate is directly related to the health and fitness of a person, and hence is important to know. You can measure heart rate at any spot on the body where you can feel a pulse with your fingers. The most common places are wrist and neck. You can count the number of pulses within a certain interval (say 15 sec), and easily determine the heart rate in bpm.

Body temp sensor function

as i'm just trying to make it a short descreption, i will give more details about this sensor to whoever intersted.

if you are intersted in repeating this project please send me private message with your email and i will contact with you as soon as possible.

Basically a limited FitBit for the finger? FingerBit?

Aug 15, 5:28PM EDT0

Is there a way for it to detect and collect more information?

Aug 15, 3:09PM EDT0

Can this be used to gather information in relation to Sleep Apnea?

Aug 15, 4:54AM EDT0

Can I use the Arduino software with other AVR boards?

Aug 11, 4:14PM EDT62

Yes, although it may require some modifications to the Arduino core libraries.

Aug 12, 5:31AM EDT55

What modifications?

Aug 13, 2:35AM EDT32

Do you plan to bring this to market as a product?

Aug 11, 7:46AM EDT0

I was thinking about marketing it when I finished developing it, do you have any ideas or offers?

Aug 12, 6:23AM EDT0

Where can I learn more about Arduino?

Aug 10, 12:30PM EDT70

you can watch Arduino tutorials from here

I want to design my own board, what should I do?

Aug 10, 12:29PM EDT30

The reference designs for the Arduino boards are available from their specific product pages. They're licensed under a Creative Commons Attribution Share-Alike license, so you are free to use and adapt them for your own needs without asking permission or paying a fee. If you're looking to make something of interest to the community, we'd encourage you to discuss your ideas on the hardware development forum so that potential users can offer suggestions.

Aug 12, 5:48AM EDT76

Ok, I'll check it out, thanks

Aug 13, 2:19AM EDT84

Can you link it to an app on a phone?

Aug 10, 9:50AM EDT60

it is already linked to an App for heart patient and another app for the Doctor

Aug 10, 10:43AM EDT30

That's a very good idea

Aug 13, 1:40AM EDT74

What is Arduino?

Aug 10, 8:58AM EDT45

Glad you asked, I have a great introduction page on Arduino, click here to read it.

Thank you

Aug 13, 1:52AM EDT23

Which are the official Arduino boards?

Aug 10, 4:12AM EDT49

The official Arduino boards are the ones listed on the product page. These are boards whose manufacturers work with the Arduino team to ensure a good user experience, compatibility with the Arduino software, and a quality product. In return for their status as official boards, the manufacturers pay a licensing fee to the Arduino team to support the further development of the project.

In general, we restrict use of the name "Arduino" to the official boards. If you find a product under a different name but described as "Arduino compatible", it’s probably not an official board and doesn’t fund continued work on the project.

Aug 12, 5:50AM EDT28

Got it

Aug 13, 2:35AM EDT24

Can I program the Arduino board in C?

Aug 9, 10:37PM EDT0

In fact, you already are; the Arduino language is merely a set of C/C++ functions that can be called from your code. Your sketch undergoes minor changes (e.g. automatic generation of function prototypes) and then is passed directly to a C/C++ compiler (avr-g++). All standard C and C++ constructs supported by avr-g++ should work in Arduino. For more details, see the page on the Arduino build process.

Aug 12, 5:34AM EDT1

Where are you from?

Aug 9, 6:48PM EDT66


Aug 9, 11:39PM EDT43

Do you plan to continue working there or you'd like to try it abroad?

Aug 13, 2:06AM EDT62

Can it be used to check pulse-ox levels as well?

Aug 9, 4:36PM EDT41

we already monitored it while programming but we didn't add it to the "Heart patient" App.

Aug 9, 11:45PM EDT66

Why is that?

Aug 13, 2:18AM EDT33

What do you mean by open-source hardware?

Aug 9, 10:50AM EDT0

How is it powered?

Aug 9, 8:38AM EDT25

I used two batteries, I got them from a Laptop battery . The only problem with the power was that i need a high current 3000mA or 1800mA and the other batteries have 300mA and it is low , so i used this type. by the way the voltage is okay because I use a regulator.

Aug 13, 1:58AM EDT68

How can I get an Arduino board?

Aug 9, 6:43AM EDT0

Sure form electronics market .. lol 

Aug 9, 11:48PM EDT0

How long did it take to complete this project?

Aug 8, 10:45PM EDT69

Almost a month

Aug 9, 11:50PM EDT64

Gosh, that's quick! What's the most difficult stage in all this?

Aug 13, 2:39AM EDT69

Arduino Logo & Trademarks

Aug 8, 8:54PM EDT0

Arduino Nano

Aug 10, 12:12AM EDT0

Can the fingertip piece be designed to transmit wirelessly?

Aug 8, 3:42PM EDT81

There are types of heart rate sensor that is placed under the wrist. But it did not sell in my country.

SO, people can only order it online, right?

Aug 13, 2:14AM EDT78

I have a great idea, and direction for this product, would you like to discuss it?

Aug 8, 12:41PM EDT0

sure, i hope so.
