Applications of Heart Rate Monitor using Arduino
- A simple project involving Arduino UNO, 16×2 LCD and Heartbeat Sensor Module is designed here which can calculate the heart rate of a person.
- This project can be used as an inexpensive alternative to Smart Watches and other expensive Heart Rate Monitors.
hello
Is it possible to use LCD I2C?
Hello
Where is the code?
can u send me the code of this project plz
Code is uploaded.
This code is showing error’s…and
Some are red in colour which is not getting executed, kindly help me out.
the display shows the high values .what is the reason for this?
this codes also shows high values like 6k bpm. can you please tell us why and what to do to change it ?
May I know where can I buy online for Heartbeat Sensor Module with Probe (finger based)?
Hi,
Could you pls help me to get the video of “Heartbeat sensor using Arduino (Heart rate monitor)”.
Also pls let me know the step by step process for the same.
Waiting for your response.
We will upload it soon.
Hi,
Could you pls let me know the advantages of this project [Heartbeat Sensor using Arduino (Heart Rate Monitor)] over the Heartbeat using Mobile Apps??
Also how can we determine the Accuracy of this project?
Hi,
Thanks for your reply.
I have assembled components based on the mentioned circuit diagram. In addition to the mentioned circuit diagram and code, I have used 1 LED interfaced with Push button. And I have used KY-039 heartbeat sensor.
But I’m facing a problem when I press the button, It repeats the text on LCD as “Place The Finger And Press Start”.
Could you pls let me know how can this issue be solved at the earliest??
Great job! Thanks for sharing it.
I’m still waiting for you to upload the code for the robatic arm. Are you planning to share the code at any time?
Thank you,
its very nice project
its very useful.
Is it done perfectly?
can you please give me directions on where to buy the components for this project and the detailed code. thanks , awaiting your reply
Sir can u please give the step by step procedure for doing this project??
Since I have choosen this project as my bsc final year project.
Please can I get the code properly and all information about this project??
Everything is in the page: circuit diagram, components, code, connection and output video.
sir how can i find the control circuit(Based on LM358)
Which software has been used for coding?
Which software we should use??please anyone give the information please…
Arduino IDE
i know im pretty late but still…
Helo sir heartbeat sensor circuit diagram doesn’t works
Can u please upload circuit diagram beard board connection video
Its not working the heartbeat 0 bpm always , pls give us the breadboard circuit connection video!
Thank you !
anybody completed this project…..???
Connections are done but lcd is showing only black boxes..Can u say why so????
I am also experiencing this problem
Have u solved this problem ??
Sir ., Can u please explain the code.
Code is so simple
Help me to understand
Where did you get the heart rate sensor and control circuit from?
can you please explain the code….
This program can use for temperature sensor??becouse use LM358
Will this code run without any errors
If you have a similar sensor and made similar connections, then yes, the code will run without errors.
if( analogRead(data)<100) could you please explain this line
Hey,
Can you plz give the link to find these components online.
We bought most of the components from a local electronics store. Sorry, couldn’t help you.
can you please describe what this part mean in the code ?
byte customChar1[8] = {0b00000,0b00000,0b00011,0b00111,0b01111,0b01111,0b01111,0b01111};

This part of the code is responsible for the “Heart” symbol that you see on the LCD.
Pls give us Breadboard connection video
Thank you!
I want to add an enzyme device in the case of heart rate less than 67 and alarm in the case of heartbeat higher than 80 possible limit modify the code
could you pls explain me the loop of this code
I had to build the control circuit due to non availability. . But now the output heart beat is coming in the range of 2000 and above.. what could be the reason
I have the same problem, did u detect the problem ??
nothing is showing on LCD after putting program
Make sure that all the connections are correct. Check if the LCD is working with Arduino or not (like displaying “Hello World”). Try to change the Pins of Arduino (which are connected to the LCD). I assure you that the code is tested and works well.
Hello can you tell me where can buy the clip to insert finger and control circuit or heartbeat sensor? Can you email me the link please? Thank you..
Sorry. We bought the sensor (and the clip) from a local electronics store. Not sure about its online availability.
What is the store name?
Modern Electronics
why are you using count = count * 6?
We are taking the count for a period of 10 seconds. This result is being multiplied by 6 to get the beats per minute value.
ravi can you show me how to make finger clips and control circuitry? thank you
how to upload this code in ardino and what is the process.
Connect your Arduino to the computer and open Arduino IDE. Select the correct Arduino board and PORT. Type in your code and click on upload.
Hello! can anybody help me please ! I realised this project and I’m facing a problem. I used a KY 039 detector wish is made with a phototransistor and photodiode. When I place my finger in it the lcd screen shows an anormal response like 6024 BPM . I don’t know what the problem is. Give me some heeeelp pleaaaaase . Thank youuuuu
please how can i get the CIRCUIT diagram for the control circuit based on the LM358 and its components involved
I have already given the circuit diagram of the control circuit using LM358.
Please what are the limitations of the project
What to do if i wants to calculate data continuously without pressing the button(but measure for 10 sec when it gets a pulse) and wants to show the bpm in Android bluetooth terminal?
Where is the logic explained
Please explain the code
Sorry i need the numbers which introduce that heartbeart sensor with probe…and also the number of that controler circuit with LM358….because i want to buy them online.
What if i use KY039,do i need to change the code or to change the gain???
Is it possible to connect (join) this circuit with the temperature sensor in order to display the BPM and the value of temperature of surrounding at the same time with the same LCD????
Please i need your response…help!!!!!!!
Sir may i ask the features of this system about 4 feature please thanks it would be a huge help
Please whenever I measure the heartbeat it’s in Thousands
instead of Tens
Where can we find the heart rate sensor?
Can this work without the LM358? I connected the data pin of the sensor into A0, ground to ground and power to 5v.
Sir please can you help me out
Whenever I measure the heartbeat it’s result is always given in 6054 please kindly help me sort this very problem
WHY DID U CHOOSE FIRST OP AMP`S AMPLIFCATION FACTOR IS 1001?
IS THERE ANY SPECIFIC REASON?
How can I get this computer for making heart beat sensor.
Can not see the code
pls post
Code is already uploaded in the page. Please check it once again.
Hi
I built the circuit but it’s not working… Can you please help me with step by step process.. How to connect n wat to connect..
Waiting for your response..
sir when loading the prgm ,finding error”lcd.createChar(1, customChar1);”
Hello….i have given the circuit connection and uploaded the code but it is not working……i have used 3 pin heart rate sensor
Which software were u used for this code?
Arduino IDE.
Code is perfect….
Can i use KY-039 heart beat sensor?????
THERE IS NO DISPLAY
the lcd display doesn’t show anything . why this happened and also in video you say 20 k pot and required component show 10k pot.
Where is the code?
Code?
From where I will buy Heart beat sensor with probe ?
Can i use KY-039 heart beat sensor???
Sir what is the meaning of 330r resistance is it 33 ohm or 330 ohm???
TOO NICE.try attatch the code on my email please.
Hello my friend, would you show me how did you calculed the OPAM?,
Is it possible to connect or power this through a 5 v battery
Lcd display doesn’t work please send the how over come on this problem.
can anyone please explain the code…..
Hi,
Could you please upload the code of the project please or send it to me by email? I need it as soon as possible! Thanks!
if(analogRead(data)<100) stands for what?
Hi,
i have used little different heartbeat sensor(with finger probe) but did the same connection and tried to connect to the system.
The code is error free but im not able to select the port, i really dont knw wat is the problem
can anyone please suggest me wat can be the error in connection?????……..
