Hey, nice project, congrats..
I am making a similar project, but using a cortex (STM32F103C6), any tips?
I did it ! thank youuu
Can i directly connect this sensor with raspberry pi 4 ? Or should i use any ADC ?
Hi there surtr tech
where exactly do I put the MAX30102 on the bread board
waiting for your reply
thanks
Hello, I tried editing but when I go on «serial plotter», no curve is displayed. Do you have any idea where this problem might have come from?
thank you very great video and instructions
nice video i used the other module of the buzzer but i have a problem when i connect it, as The tone works continuously without stopping, so how can i solve it??
One question, were did you conect the black cable in the Arduino board, for example the red cable is in the 5V but I don't see were you put the black cable, can you tell me please?
Hello, could you help me understand how I can adapt this approach to an arduino nano ble 33 board??
Sorry in the video I said that the module cost 10$, it's actually 2-3$
~4.3 in my CD MX..,,and your like👍 and suscribe ,to your Chanel..
what is the name of the program? can i use Dev c++?
have you made open the resistor or cutting something at your max30102??
We do the same project but we need to measure hemoglobin instead of heart rate can you help us to find the code of hemoglobin
4:46 Instead of getting continuous values, is it possible to get a single value in the serial monitor? Please help
after the first beat, my buzzer keep play sound (higher frequences than the beat deteced sound) and it keep play that sound infinity.
Please if I want to make a patient monitoring for huspital purpose which monitor can I use ?
having an issue where the Arduino isnt actually reporting the information on the serial plotter or serial monitor and the TX and RX LED's are not flashing as in the video. Is there anything I can do about this?
hello surtrtech, can we get the heartrate, spo2 and temperature in a single program?
Hey Bro, can we change A4 & A5 to any other pins on Arduino?
it's great! but how to get and display the spo2?
Hello! Can we use pulse sensör and lcd with Arduino Lilypad? Can you write the name of hardwares. Thank you.
Hello, I have a OLED 128*64 1.3 What changes should I make to the code?
instead of placing a fingertip, can it be used with our wrist?
The Best!
hello this is nice project and video. i wanted to ask about the value 7000 for detecting finger on the sensor. what's that value mean? how could you assume that value 7000 as finger already on the sensor? thank you in advance and sorry for my bad english.
When there is nothing in front of the sensor you'll get values 0, maybe 100, but when you put finger (not even touching) you are guaranteed to get like 15000, 7000 is a safe value to assume the finger is away
can i use the same code for r MAX30100 sensor?!
Good work, but i have a little query. The BPM values are varies rapidly. How to stable the values of BPM as like the other products available in the market gives more stable BPM values
Use a rolling average filter
@@kugelblitz9137 what is rolling average filter? I have the same problem, max30102 gives me non stable data
How can we measure body temperature using this sensor
is this max30102 have a design error like max30100 pllzzz tell me i ordered that sensor and tomorrow is delivery date pllzz help
What is the power source?
Is pulse sensor on tinkercard??
Hello! Great video! :) I thought about maybe making one for myself to monitor my health and if anything bad happens during my sleep it could dial my family. I'm thinking about making a nice case for it. Have you seen any or have any ideas? :)
Well better get one of those module that sticks to the body (ear or finger clip) + GSM module to send a text, you can go furhter if you're using IoT
wow nice, but I need support.
can i use MAX30100?
Hi, Example5_HeartRate run fine, I get 66 bpm, but with Example8_SPO2 I get 166 BPM ! SpO² 98%
Can i do it without buzzer?
The library link you provided in the description, is for max30105, 😒😒
So I want to make the model u made but without the buzzer or OLED screen, is there a separate code for that or do I use the same code. I want it to look like what you did in the video before you added the OLED screen and buzzer where it showed the BPM results in the serial plotter
Hello, yes those are examples from the library, you can find the library in the link below the video, there's one for the serial plotter, and one that prints the IR, BPM and Average BPM, if you want to plot the BPM, you can try the "Example5_HeartRate" and in the serial.print functions leave only "beatsPerMinute" and start the serial plotter instead of monitor, I think you may see the BPM values as a graph
SurtrTech So I’m looking through the libraries and I am having trouble finding it, I’m a beginner and I really don’t know my terms, do u mind naming off the libraries/codes that I would need?
@@mayankgudi5919 Well first download the library "SparkFun_MAX3010x_Sensor_Library" from the link or from here: github.com/sparkfun/SparkFun_MAX3010x_Sensor_Library
Once downloaded go to Arduino IDE -> Sketch -> Include library -> Add .ZIP library -> Select the .ZIP library you've downloaded
Then Arduino IDE -> File -> Examples -> "SparkFun MAX3010x Pulse and ..." -> Go there and you'll find all examples I used and some other ones just select and you'll aready have a code to upload.
For your case: Example 4 will display raw values on the serial plotter, and also shows you peaks when you place your finger.
Example 5 will display the IR values (Raw), the current BPM and Avg BPM on the serial monitor but you can remove the IR and Avg BPM to show only the BPM then display it on the serial plotter if you want...
SurtrTech Thank you so much, I finally found it. The video was amazing and thank you for guiding me. I am looking forward to trying this project out myself. Thank you again!
Max30102 press key ..?problem..?
Can someone send heartrate.h file I can't find it in library
Hello, i have a project in which i have to show both spo2 and bpm can u please tell me how to do it.i.e source code and schamatic ckt for simulation in proteus
Hello, Never used it with Proteus before, and I couldn't fit both codes in the Arduino as I said in the video, flash memory space problem.
hi bro
do u have any idea making this happen using atmega 16 using avr stuudio 4 as ide
like collecting bmp and spo2
please let me know and help me converting the code
thank you
Sorry, no idea for the moment.
Hi bro
Like if ur friends know ask them once
And let me know bro coz i need your help..
Thank you
U can message me on WhatsApp +91 9441516627
Hi SurtrTech, i was able to get mine working but my heart rate readings are not steady they keep changing with wide margins.
Same with my project. I think you need to filter the output first with a digital filter.
Sir PLEASE HELP ME TO CODE USING RELAY CONTROL
kapan pasang buzzernya?
Hi can i simply combine the heart rate algorithm and spO2 together or do i need to specifically organize it for the whole thing to work?
Well the SpO2 code sets the module to other parameters than those used in BPM measuring... but you can give it a try and combine the functions and check if ther results are okay.
N.B: I tried this using OLED and it didn't work...
@@SurtrTech for lack of flash ?, or ram? ,, throw junk data? ,, or what happened ?, because I use to get the 2 data...
@@angelruiz825 I had flash space problems, I tried in many ways and used less global variables but I failed... and it didn't work with the OLED
Since there is so much data from spo2 you will need to implement can we use fifo to store data temporarily for flow control?
Hello, could you show how to make spo2 code visible on the oled screen? Im trying to implement spo2 code from example, but im having hard time to do this.
Hi, I had a lot of trouble uploading the SpO2 code to the Arduino too, it's due to memory space, and the OLED kept freezing unfortunately so I ended only with the BPM part
@@SurtrTech The 30105 has more functions, so maybe this library uses more resources. Isn't there a specific one for 30102? ,, Or could it work with the 30100? ,,, I imagine you tried to reduce the buffers [100] to [50 ] or [25] ,,? ,,, / only show the "hr" and "spo2" in the oled, without the other unnecessary data / make captures of "spo2" and "hr" using different blocks { },,with local variables within each block or call a function, outside the void loop to spo every so often(not at the same time) and show the average of them during a certain time, for example take data 3 seconds of hr, then average them and show them held in oled, then take 3 seconds of spo2 and do the same This way you would show averages that every 6sec. were updated in the OLED ... or stop for a second every minute to take spo2 since this data does not change much or very fast / in a more extreme case take 8-bit data (uint8_t) in the chain but before catching them, get a rule ratio of 3, so that they do not exceed 255 (8 bit arduinos like (at328/168/2560) use a lot of memory, when using variables of 16 or more bits, because they are native to 8 bits) ../ do not use or show anything that is float / do not show logos or animations while showing the data / use only the smallest font (size 1, "6x8pix") / show on one part of the screen a "hr" data during 1 print in oled and in another print spo2, (the eye does not I would notice it) / use a board with 32u4 (2.5kb ram) or mega2560 (8kb) (but the device would grow) / modify the libraries ... Manage another lighter library of oled like this th-cam.com/video/XYBcr1KpN3Y/w-d-xo.html perhaps it would avoid all the above, this supposes using less sram & flash..I could not check all this because my provider will bring me 30102 in 1 week..I will try it in promini 328p, although I already ordered a teensy lc, since I want to add module m.sd (or Eeprom) + accelerometer + display graph in 128x64..I suppose this could do the task (8sram@32bit)..
@@angelruiz825 This library is standard for them all... the problem is that the parameters for BPM are not the same as the SpO2 code, so you have to add all of them... you can maybe modify the libraries or reduce the codes further.
The main problem was also the use of the OLED, didn't start at all.
Only trying will get you to results.
After I upload the code into Arduino, the serial plotter says "MAX30105 was not found. Please check wiring/power. " The TX, RX and the LED on the MAX30102 aren't flashing. How can I deal with that?
Did you solve the problem? Because I have the same problem.
hello dear I am using this sensor with other sensor but with this library it's affect the heart beat rate how can i make this reading like an interrupt ?.
thank you
On Uno only pins 2/3 can be used as interrupt's I suggest adding a button to launch the measuring function that will do multiple readings before displaying the result and continue other things...
Hi, i have a project in which i have to show both spo2 and bpm can u please tell me how to do it... I am a complete newbie
You can try to combine them (two codes from examples).
Wanted to do that with my OLED wired... it didn't work.
Why does it says redefinition of 'void setup()' . I cannot compile the sketch of Example8_SPO2.ino . Can you help me please
Do you have other tabs in your sketch?
Or do you have two "Setup" functions in your code?
I would like to know how to implement the code to insert spo2 in the display.
what is SPO2
Hola SurtrTech
al cambiar la resolución de la pantalla a 128*64 el sensor deja de tomar la lectura, si se mantiene la resolucion a 128*32 funciona correctamente, puedes ayudarme ?
I have no idea, it probably creates a display distortion, if you can start from scratch without animations or anything and test it, first just print the BPM and then re create the bmp images
Hola, ¿Lograste resolver ese problema?, y de ser asi ¿Seria mucha molestia explicarme como lo hizo? o en el mejor de los casos ¿Pasarme las modificaciones que hizo al codigo?

Hello
I am using ESP32 but the MAX30102 sensor gives an error
"MAX30105 WAS NOT FOUND"
What should I do?
Hello there! Did you succeed ?
@@apocaylips33 No!!
Hi, its a great video and very helpful me. but i really need spo2 code for my project, can you help me to get the spo2 code?
Hi, you can find it here after download this library. Let find it in examples.
github.com/sparkfun/SparkFun_MAX3010x_Sensor_Library
You can check the link it's where you'll find the library and within there's the SpO2 in examples
Hi,
My own, doesn’t work, I made all like you, my red light isn’t on and I don’t get a graph in the serial monitor ether. Pls help me
Hello, wire your module only and upload the i²c scanner code, playground.arduino.cc/Main/I2cScanner/ and check if a device is detected or not... if you soldered the module yourself check if it's good
Hi, Does this module work with 3.3V ?
Yes
@@SurtrTech thanks for the Swift feedback!
How can i convert the spo2 results into % ?
Hello, sorry I don't know what you meant but the values given are actually a percentage, 95% 98%... or do you want them like 0.95 0.98...? Just a simple divison can do the work.
😢Hello!
Where the code of spO2?
If I only want to display the value of the heartbeat, how to modify the function of the buzzer
Hello, you can remove all the functions related to the buzzer (Tone and noTone with some delays between them), do you want to remove the "hear beat animation"?
@@SurtrTech i have a private message on your Facebook. Can you see it?
@@user-uy8hq8oz5m Yes, we'll talk there :)
@@SurtrTech hey how can the animation be removed?
Can it detect the values of IBI?
Well you have BPM, little math you'll get IBI, but for precise calculation you can calculate the millis() every beat and store them on a array
Hi that s great but plz can u send me the spo2 code
Hello, it's in the library examples as well
where is spo2????
Hello SurtrTech, excuse me ! i can see Heart Rate but i can't see SpO2 😑
The code I used with the animation doesn't include the SpO2, as I said there was a memory problem, but in the examples there is one that measures the SpO2, you can adapt it to the OLED
@@SurtrTech Thank you very much !!!
can I do this with MAX30101 ?
Hello, well the library is called MAX3010x and it includes the MAX30101 too, it should be good.
@@SurtrTech SO do I follow the exact similar process as in the video for MAX3010x as well, including codes and libraries ??
@@sandeshtayde1516 Yes.
ETC Official . did you manage it with MAX30101 because i cant do this.
Hello, great project!
I currently make a project and I really need the MAX30102 oximeter, the fritzing part. I couldn't find it anywhere. Any chance you could help me and send it to me, please?
Hi, is that you who contacted me on Hackster?
Hi, unfortunately not. I saw the project there but i don’t have an account on hackster and i thought would be better if i leave you a comment here. Do you think you could help me?
@@alexandranistor6605 Well I want to help but the problem that was just a picture of the module, it's not a fully functionnal Fritzing part, I wanted to create the part but it's not working, I could send you the image I used + SVG file if you want
@@SurtrTech It's more than enough. I just need it for the fritzing scheme, to wiring it with my other components. It doesn't have to actually work.

I have half as BPM as you 😂
There is no SpO2 reading here ...
Hey thanks for the video, can you upload the SpO2 code, please? Dont be selfish!
Selfish? Well all the schematics, libraries and codes are already on the link for anyone to use... The SpO2 code is on the library example it's made by SparkFun...
As mentionned in the video I couldn't upload a code that measures both BPM and SpO2 while operating the OLED, the code was too big and the OLED keeps freezing, so I ended up with BPM only.
You can give it a try, first upload the SpO2 code from examples and then adapt it to the OLED as I did, all you have to do is add OLED libraries, replace functions and here you go.
hi, I would like to know how to implement the code to insert spo2 in the display.
thank you
Hello, I can't remember if I tried it or not to tell you if it works first.
You can try, first you install the OLED library, do the declarations like in the code I provided, then instead of showing the value on the serial monitor, display it on the OLED.
Hi that s great but plz can u send me the spo2 code
Hello the Spo2 code is just an example from the library, you'll find everything in the link below the video
