Brilliant video! I had a request, could you make a separate video on how to use MAX30102's all sensors in one time using nodemcu on any other application (blynk, ubidot, etc).
Excellent video, thanks for taking out the time to make it. I have a few ideas for another video project: It will be a health monitor with a screen that shows the following things: 1. Two digits after decimal point for better accuracy 2. Heart sine wave 3. If this sensor can calculate heart rate variability (HRV) i.e. the time between two heart beats then you can add that 4. You can also add a skin conductance sensor to show volts 5. Infrared temperature sensor I have seen several projects on youtube but no one has combined all these in one. If you like, I can collaborate with you. Let me know and I will send you an email. Thanks
I have a sensor module (MAX30102) where "SCL" and "SDA" are present. I need it to be used without any control board !!! Let's start with the reasoning: IC LM335 has a pin " ADJ " which as the 'abbreviation says deals with accepting adjustments but with the right conditions. Scl = serial clock and Sda= serial data ................ . Instead if you were using Arduino you have to connect it to pin A0 . So? ------------> SDA !!! :) Let me know it is urgent. Thank you very much.
Hi there, for some reason my sensor wont power on (no led light). Copied the wiring etc the same as yours.... any reason why this would be the case? Does the sensor need to be powered externally (not usb?)
Please check I2C commnication. Maybe your MCU is unable to communicate with the module. You can check using I2C scanner sketch (Link: playground.arduino.cc/Main/I2cScanner/) upload the I2cScanner sketch -> open serial monitor -> select the correct baud rate if the I2C communication is healthy then you should get the i2c address of the module in the serial monitor, if not then there is a problem with the connection.
@@UtGoTech Tried a new Uno, and am now getting a note saying " I2C device found at address 0x57" After that I cant seem to get the example 4 plotting code to read anything though? Do I need to modify the code at all?
Thank you very much! I have followed your instructions and it worked perfectly, but can i add something like buzzer to give a warning if the heart beats are under 60 beat/min? I tried to do so , I connected the buzzer and wrote the code in the end of the example heart rate, and it was uploaed successfully, but measuring stops in the second iteration and no readings appear … If you have any advice please?
Hi! I am using the same sensor but instead of using the arduino IDE, I'm using vscode (with platformIO to help code it). What steps should I take differently to achieve the same result?
There are libraries easily available for the max sensors for Arduino IDE. If you are using any other IDE then you have to get a compatible Library for that IDE or otherwise you have to go through the datasheet of Max sensor and find a way to get data through I2C bus.
Thank you for the tutorial! I have 2 problems, the electrical circuit disconnects and is very sensitive to the touch even though everything is connected well and no component is damaged, secondly, even when everything is connected and the red light on the MAX30102 works you can't see the graph after I put my finger on the red light. any ideas how to solve it?

hi friend, good job i have two questions , first what is main difference between max 30100 ,30102 and 30105? and second can i use them as a body temp sensor to? thank you so much
MAX30100 and MAX30102 are designed to detect heartbeats and oxygen saturation level in blood. Where as MAX30105 is designed for smoke detection. They can't be used to detect body temperature. The temperature sensor inside is only meant for internal sensor calibration and adjustment.
Hi, i connected as instructed in the video but it the sensor wont turn on and then says max30105 in the serial monitor no found, when i used the i2c scanner it says no device found. please what do i do next.
In your case the I2C communication is not working. Please check the wiring use small jumper cables in case you are using breadboard. Also recheck the connetions.
@@chikenwibor3481 I have got steady readings. Call checkForBeat() function as frequent as possible. It will help to detect heartbeat more accurately and efficiently.

Yes...arduino connect with sensor...and raspberry oprate arduino it means raspberry and arduino interconnect. I need python code bcz i implement code in arduino with help of raspberry
I think you have to program Arduino board so that it can interface with Max sensor to read data and then send it to raspberry Pi using serial or i2c interface. For Arduino you don't need python code
"Initialization of oximeter failed" is showing because your micro-controller is not able communicate with the MAX30100 module. You should check you hardware connections and make sure I2C communication is ok. You can use I2C Scanner sketch to check whether your micro-controller is detecting the MAX30100 sensor or not.
@@UtGoTech checked the connections and they were correct. But it still doesn't work I uploaded the code, but the LED does not work and I get a message in the serial monitor (can't find max30102 check...)

I have used an example sketch. In Arduino IDE goto File -> Examples -> SparkFun Max3010x. Here you can find the example sketch's. - Sorry for late reply
Easy Code is written by using existing library. The code have to be change according the library used. So you have to tell which library you are using. If you didn't installed any library yet then add MAX30100lib by Oxullo Intersecans using Arduino Library Manager. With this library you will also get some example codes which will fulfill your needs.
Just print the heart beat data in serial monitor using Serial.print function. Sending information in serial monitor is shown in the Example5_HeartRate sketch, which comes with the library. In Arduino IDE just goto File -> Examples -> SparkFun MAX3010x -> Example5_HeartRate.
I have this problem: "MAX30105 was not found. Please check wiring/power" Can someone explain to me what this is due to? it is supposed to be well connected PD: I'm using a ESP32 board
@@UtGoTech What happens if the scanner does not detect it, I already tested it and it tells me that it does not find any device, the sensor led does not turn on either, what do I do?
If the scanner app doesn't detect your MAX30105 module that means your ESP32 board is not able to communicate with the MAX30105 module. Check whether you have connected it to the I2C pin or not.

Hello, This is a nice video. I hope to use this sensor with raspberry pi 4. do you have any video or code for raspberry pi
Currently don't.
Hey Bro, can we change A4 & A5 to any other pins on Arduino?
No. It can't be changed. Hardware I2C pins can't be changed.
@@UtGoTech okay, so what pins to attach scl and sda if i am using esp32 ?
You can find out in datasheet of your board.
@@UtGoTech okay, thank you so much 😃
Hello i make project just like you but when i put mu finger on the sensör light is going off why and other question i open serial port but i cant see the graphic just like you why bro
Have you soldered the male headers into the sensor?
@@UtGoTech yes i check and do you know serial port i cant see graphic just like you
First check if raw data is showing in serial monitor or not?
I cant find on the internet about the heart rate hat arduino can you make one about it please!!!!!!!!!!!!!!
Which one?
@@UtGoTech the heartbeat hat arduino I cant find it anywhere
Can you specify module name.
@@UtGoTech Interfacing MAX30102 with Arduino + BPM measure project with OLED + buzzer.
But with a heart rate hat component
Google it. You will get some purchase links.
Hi! I connected it the same way the video showed but the led is not turning on. What could have happened?
Check for loose connections.
I suggest you to solder the pins.
Have you checked the i2c address of your module?
@@UtGoTech hey, my module led is also not turning on and i hv also checked the i2c address but where should i chang this address in this code?
You don't have to charge the I2C address. If you are getting the address that means communication is ok.
Hey bro, I’ve seen the numbers but a cannot know exactly what they mean 😅 once that normally the value used to be like 90 but i seen like 880, could you explain it?
The value you are getting is not heart beat rate. Those are the values from the sensor/ADC.
i'm doing this project right now but my red led on sensor wasn't blinking can you help me out
Check if microcontroller and Max module is communicating or not.
@@UtGoTech in i2c scanner code it was displaying not found
That means microcontroller is not able to communicate with max module.
Check your connections and look for loose connection
Sir please share the library
Just follow the video. You will see inthe video.👍
hello, can i have the program??
Code is given in the example sketch
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?
Are you getting data in serial monitor ?
Good evening, no I get nothing. As soon as I telecast the program, the LED goes out.
I really need your help please 🙏🏼
Use I2C scanner sketch to check it Arduino is detecting your module or not.
@@UtGoTech Thank you for your help! I have an other question about the arduino code for calculating heart rate, i don’t understand in arduino code : « long delta = millis() - lastBeat ; lastBeat = millis() ; beatsPerMinute = 60/(delta/1000) » thanks you !
I do all the steps but this error comes
: Example8_SPO2:30:10: fatal error: MAX30105.h: No such file or directory
how can I fix that
Have you installed library for the MAX sensor ?
to activate 30102 Press key , key? ..?
Please explain what you are asking
@@UtGoTech
Code for blood oxygen
[ Serial.println(F("Attach sensor to finger with rubber band. Press any key to start conversion")); while (Serial.available() == 0) ; //wait until user presses a key Serial.read(); ]
I pressed all the available keys, but it is not converting.
I have a another doubt,
if I connect MAX30100 with another sensor in arduino board, the heart rate goes zero and spo2 showing references values..clearly pulseoximeter is not working. But if I connect pulseoximeter with arduino, heart rate and spo2 is showing and the pulseoximeter is working. Do you know what is the issue ? ( when I connect another sensor, max30100 is not working. )
Which code you are using
What other sensor you are connecting
I have error in code at the line of particular sensor
Share the error message?
How to get actual value of bpm using the graph obtained
for bpm you have to use separate code.
You can get the bpm code in the example sketch
Hello, my connections are correct and my sensor power on but when I place my finger on it the sensor is not picking up a pulse but instead it is just showing a straight line on the serial plotter. If anybody has any suggestions that would helpful
Are you getting raw values from sensor?
In my max30102 sensor led is not blinking and says intializing pulse oximeter failed what can i do sir
Look for connection issues, loose connection.
Hi bro I am facing the same problem what did you do to solve this problem kindly help me
Solder the male headers. Make sure the connections are not loose.
hi, thanks for the video. Could you tell me please how red and IR values are calculated, what is their maximum range?
Those are the values coming from respective ADC's
Is fingertip necessary
Yes
how to get bbm and spo2 in one code !!
The Example 8 provided with the SparkFun MAX3010x library contains both heart rate(bpm) and spo2.
so you only need 4 pins, not all 8 of them?
Yes
@@UtGoTech thanks.
@zwtsch welcome👍

Can you help me...i need max30102 sensor code in python programming..bcz i control arduino with help of raspberry pi....sensor connected with arduino.so i need python code!!!!!
You are using Arduino board in between Max sensor and raspberry pi. Am I correct?
Yes...arduino connect with sensor...and raspberry oprate arduino it means raspberry and arduino interconnect. I need python code bcz i implement code in arduino with help of raspberry
I think you have to program Arduino board so that it can interface with Max sensor to read data and then send it to raspberry Pi using serial or i2c interface. For Arduino you don't need python code
I know..do not need python code.. without python code it is possible..but python code is requirements of my uni. Project..its mandatory
Sorry currently I don't have python code to do so.
My sensor is heating and.. In serial printer it is showing max30102 not found. Please help me bro
How much voltage you have given to the module.
There may be some chance that you have got faulty module
@@UtGoTech I sorted it out bro... Just removed the Resistors... It's working fine now
Max30102 not working any modification needed for scl,sda,pins
No modification is needed for this module
Are you using different module
Bro mera sensor max30100 me light nhi jal rha iska MATLAB kya hoskta hai ????
Also showing initialisation of oximeter failed
I'm using with esp32
"Initialization of oximeter failed" is showing because your micro-controller is not able communicate with the MAX30100 module.
You should check you hardware connections and make sure I2C communication is ok.
You can use I2C Scanner sketch to check whether your micro-controller is detecting the MAX30100 sensor or not.
@@UtGoTech it is showing initialisation failed :I2c error
Tell me the solution should I remove all 3 resistors from sensor and connect external resistors????
why do my lights go on sometimes and off sometimes then just decide to not work at all
its so frustrating😵💫
Which type of battery you are using ?
@@UtGoTech i use an uno board (usb cable to computer
Make proper connections. Solder the male headers.
it doesn't work with my.. the led not work What should I do
Check for loose connection.
@@UtGoTech checked the connections and they were correct. But it still doesn't work I uploaded the code, but the LED does not work and I get a message in the serial monitor (can't find max30102 check...) I read online that I have to remove the 4.7k resistor and install it externally, do you have any idea how to do that?
heelo can i take the codes please
I have used code from the Example Sketch of the Arduino IDE.
hello, link to the code? thx
I have used an example sketch. In Arduino IDE goto File -> Examples -> SparkFun Max3010x. Here you can find the example sketch's.
- Sorry for late reply
Sir please give the source code of max30100
Easy Code is written by using existing library. The code have to be change according the library used. So you have to tell which library you are using.
If you didn't installed any library yet then add MAX30100lib by Oxullo Intersecans using Arduino Library Manager. With this library you will also get some example codes which will fulfill your needs.
@@UtGoTech sir can I use max30100lb source code in max30100 sensor please reply 🙏🙏🙏🙏
This library can be used with MAX30102 and MAX30105 modules only. This library doesn't support MAX30100 sensor.
Can i get the source code ?
You can get the sketches in Example.
Sir please share the code for finding both heart rate and spO2
It can be found in the example sketch.
ممكن تبعتلى الكود 😢😢
You can find code in the Example Sketch of Arduino IDE.
How can I just want the information in the serial monitor not in a display how can I do that?
Just print the heart beat data in serial monitor using Serial.print function. Sending information in serial monitor is shown in the Example5_HeartRate sketch, which comes with the library. In Arduino IDE just goto File -> Examples -> SparkFun MAX3010x -> Example5_HeartRate.
Code
It is given in the example sketch which comes with the library.

Sorry for you inconvenience. I will try to improve my vocals.
I have this problem: "MAX30105 was not found. Please check wiring/power"
Can someone explain to me what this is due to? it is supposed to be well connected
PD: I'm using a ESP32 board
Communication error occurs due to loose connection or wrong connection.
You can also use I2C Scanner Sketch to check if the modules are communicating or not.
@@UtGoTech What happens if the scanner does not detect it, I already tested it and it tells me that it does not find any device, the sensor led does not turn on either, what do I do?
It may be because I have not soldered the sensor, but what if I do and still the problem persists?
If the scanner app doesn't detect your MAX30105 module that means your ESP32 board is not able to communicate with the MAX30105 module. Check whether you have connected it to the I2C pin or not.
