****************************************************************************************************************************************
In this DIY IoT Project, we will make an IoT Based Smart Health Monitoring Device that can measure SpO2 (percentage of oxygen in the blood) and heart rate in BPM (Beat Per Minute). We will interface MAX30100/MAX30102 Pulse Oximeter with Nodemcu ESP8266 Wifi Module. The Best part of this IOT project is that you can connect this device to an Android application Blynk that will record and regularly update the data for both SPO2 & BPM on the Blynk Dashboard.
As there is an availability of online data, so this project can be used to monitor the health of a patient online. The pulse oximeter available in the market is very expensive, but with this simple & low-cost pulse oximeter module, we can make our own device. So let’s learn how to make MAX30100 or MAX30102 Pulse Oximeter with ESP8266.

Your tip about the wrong pullups for the MAX30102 board is pure gold! I thought the sensor is totally dead, but after cutting the track that provided 1.8V and soldering a wire to 3.3V now it is finally working with the MAX30100 Examples.
@bbogdanmircea @howtoelectronics
you made changes same way as show in this video for max30100??
I am using max30102 with sparkfun max 3010x lib but even example code is not working
Hello bbogda.. pls help me how to cut the sensor
brother how can I do it with a max30102 and esp8266? And if the case were an arduino uno ?, I have an arduino uno that when loading the spo2 library throws me a memory error, like it is exceeded
@@krushantvyas9039 Hi same here too , have u got the output
i realize it is kinda randomly asking but do anyone know of a good website to watch newly released tv shows online?
Great video. Thanks. I wanted to ask if you were able to cross check the value with other medical devices and see if they correlate or how accurate are they?
Nice. Would be nice to make a finger case with a 3D Printer so that readings are stable!
Nice project 👍
Could i use max30102 instead of max30100?
Which app is used for stimulating? And which app or website is used for ckt connections for showing purpose sir?
Sir same code not working for max30102?
Sir oled display is in showing initializing and then failed how can i fix this?
How to cut the 1.8v track and connect 3.3v ...please help
How to make dual sensor max30100 in arduino?
How to use max30102 with nodemcu
@How To Electronics : Can you please let me know what is the cable connected fro Max30100(Brown color cable) ? If i provide power 3.3v & gnd to Max30100.. it will glow LED right ? In my case it is not.. can you help me.. On LED screen it is only showing initializing ...
The Max30100 has design issue. You can follow my website article to learn about fixing the issue.
si hago sin la pantalla OLED , solo quitaría la parte que tenga en el código : oled.
Can we make iot thermometer
what jumper you made on sensor max30100 sir?
Check website article. Its explained there.
Does this work without the lcd? And is it need to put jumper wire in rhe sensor?
It will work without OLED display. And you don't need to put jumper wires in the sensor if the sensor is working well.
How To Electronics hi my max30100 leds is glowing but when i upload and open serial monitor i get softwdt reset and initializing failed. Can you help me sir
How to do this with ARDUINO UNO, offcourse without iot thing i just need to display value on screen. Will same code work ?
There is already another project with arduino on my youtube channel
ESP 8266.WiFi.h directory not found dikha Raha Hai , please solve my issue
I will need to be this materials
Can i use MAX30100 without arduino?
You need a microcontroller.
What software is used for to the design the circuit diagram pleas tel me the soft war or give me the link to dounload that
Fritzing
@@HowtoElectronics thanks a lot
@How To Electronics Hi.. I liked the project and tried making same.. I dont want Blynk to be used.. just display on OLED is enough for me.. i am facing one issue while uploading sketch.. can you please help me on this.. The error is :

Error compiling for board NodeMCU 0.9 (ESP-12 Module).
Looks like u have selected the wrong board. And if you don't like Blynk then you can simply do this project using Arduino. There is another video for that. Check my other videos.
Very nice explanation. I construct it successfully. Next day i suddenly disconnected GND pin from breadboard and sensor MAX30100 is not working. I think it's SCL, SDA pins are shorted with VCC . Is any other chance to recover . I think not ☹️☹️☹️☹️☹️
May be excess current damaged the sensor as there is no reverse polarity protection.
@@HowtoElectronics Thank you for quick reply. I think reverse polarity protection should be enabled in all most sensitive sensors use in MCU because beginners & hobbyist do a mistake.,🙏🙏🤔🤔🤔🤔
A simple diode can be placed for reverse current protection.
Only displaying initializing pulseoximeter... Can you help me to troubleshoot this problem.
bro same problem, did you find any fix to this?
Same problem did u get any solution?
Hi bro i tried to display the data of max30100 in thingspeak but it always show 0 , they told me that max30100 values can't be shown on thingspeak is it true ? should i try blynk
Yes its not possible on thinkspeak. You should try blynk or ubidots
@@HowtoElectronics I'm thinking to connect to make a smartphone application that gets the data from the servers than display in the app which one do you advice me to choose blynk or ubidots
Both are best.
@@HowtoElectronics But they told me that if i use blynk i can't make a personalized app and collect the data of the sensors that are in blynk
The heartrate is fluctuating
can use any esp8266?
Can it use Max30102
How to get the auth token
😂 machan therla da
Any design issues for max30102
Hello pavan,, is that works for max 30102
not working :( max30102
My MAX30102 has same design issue, you need to cut pullups to 1.8V and solder them to 3.3V
Can i get code link plz?
Link in the description
I am Getting this exception, please help.

These cheap sensors are very inaccurate and all the video makers say that they didn’t put their finger properly! Really? Is it too difficult to re-record the screen readings and then include that in the video? Yes it’s too difficult because no matter how hard you try these DIY sensors will always show such disturbing and unstable readings… 👍🏻 Useful for learning basics…👎🏻 Useless if you want to use it for medical purpose.
Surprisingly none of the DIY TH-camrs ever show comparison between real oximeter and their DIY project! Because they fail to show trustable readings.
Bro same problem..it is fluctuating ..how to solve it brother ?
