IoT Based Smart Pulse Oximeter with NodeMCU ESP8266 & MAX30100 Sensor

[@bbogdanmircea]

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.

[@krushantvyas9039]

@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

[@Ankit-mq6em]

Hello bbogda.. pls help me how to cut the sensor

[@marcelovaldez8035]

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

i realize it is kinda randomly asking but do anyone know of a good website to watch newly released tv shows online?

[@pavankumarvaranasi3051]

Sir same code not working for max30102?

[@peyl6794]

Could i use max30102 instead of max30100?

[@bbogdanmircea]

Nice. Would be nice to make a finger case with a 3D Printer so that readings are stable!

[@electronic7979]

Nice project 👍

[@ramofficial1343]

Sir oled display is in showing initializing and then failed how can i fix this?

[@ehsanulkarim]

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?

How to cut the 1.8v track and connect 3.3v ...please help

[@3vedinishit]

@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 ...

[@HowtoElectronics]

The Max30100 has design issue. You can follow my website article to learn about fixing the issue.

Can i use MAX30100 without arduino?

[@HowtoElectronics]

You need a microcontroller.

How to do this with ARDUINO UNO, offcourse without iot thing i just need to display value on screen. Will same code work ?

[@HowtoElectronics]

There is already another project with arduino on my youtube channel

Can we make iot thermometer

[@kenpaul8269]

Does this work without the lcd? And is it need to put jumper wire in rhe sensor?

[@HowtoElectronics]

It will work without OLED display. And you don't need to put jumper wires in the sensor if the sensor is working well.

[@kenpaul8269]

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

what jumper you made on sensor max30100 sir?

[@HowtoElectronics]

Check website article. Its explained there.

can use any esp8266?

si hago sin la pantalla OLED , solo quitaría la parte que tenga en el código : oled.

[@IMRANKHAN-we9un]

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 ☹️☹️☹️☹️☹️

[@HowtoElectronics]

May be excess current damaged the sensor as there is no reverse polarity protection.

[@IMRANKHAN-we9un]

@@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.,🙏🙏🤔🤔🤔🤔

[@GaaneJaaneAnjaane76]

A simple diode can be placed for reverse current protection.

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

[@HowtoElectronics]

Yes its not possible on thinkspeak. You should try blynk or ubidots

[@lifechangingproduct7301]

@@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

[@HowtoElectronics]

Both are best.

[@lifechangingproduct7301]

@@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

[@HowtoElectronics]

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.

[@sleepyvoyager]

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 KZbinrs 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 ?
