Sir i have followed the same procedure. As I have removed three resistors and i have used two 4.7k resistors for external connections. Even after all those efforts, it is showing "initializing pulse oximeter failed"

I bought max30102 (green color) I cut tracer as per first method you show. Still LED of sensor does not glow. I ran i2cdetect and it identifies my sensor at 57
Hi Guys We found that after following the steps ,It still dont work in this case try this. After some work around we found out that to use 5v for the max30100 sensor instead of 3.3V and it works. Hope this helps.
Red light glowing and showing "initializing pulse meter sucess". But in the next line bpm, spo2 data is not showing. Instead of that different symbols are displaying.
sir, i have a problem about the inaccurate measurement of the sensor. the sensors is connected, the led light is on. but the number of measurement isn't correct, what should i do sir? please help me. 🙏
your method does not work check your comment section more than 90% people have tried and it didnt worked out is their any other alternative i already removed all my three resistors

Can you post a schematic of the external resistor added on Breadboard? The video was not very clear. Thanks in advance.
thank you sir, you have been infinitely more useful than any of my TAs or profs in solving this issue
Does it work for you

I followed this video as shown, but still not working
MAX30100 was not found. Please check the wiring/power.
I bought max30102 (green color) I cut tracer as per first method you show. Still LED of sensor does not glow. I ran i2cdetect and it identifies my sensor at 57
So, change tga same i2c address in the code and try again.

Hi Guys
We found that after following the steps ,It still dont work in this case try this.
After some work around we found out that to use 5v for the max30100 sensor instead of 3.3V and it works.
Hope this helps.
Did u provide 5V to Max30100 after using the second method?
Sir, can the same method be used to solve the problem with MAX30102(the sensor is in black color)
Bro the red light glows....but it cannot read any signals....it shows 0 pulse and 0 spo2 on monitor

I tried the second method but the red light on the sensor doesnt turn on and it gives the failed to initialise msg. Is the second method useless then?
Can you mention the External resistor type and watt
sir, i have a problem about the inaccurate measurement of the sensor. the sensors is connected, the led light is on. but the number of measurement isn't correct, what should i do sir? please help me. 🙏
Did u did modification of the circuit
Boss can u give me idea of oximeter housing idea
thankssss a tonnnn🥺 first method worked
Which one better max30100 or max30102??
El primer método no funciona con max30100 y esp32 nodemcu. Sería bueno que aclares porqué conectas el pin INT, algún fundamento simplemente. Saludos.
Thank you so much bro it work....😊
Thank you, can get the code?
Yes, please drop a mail on askus.electronicsinnovation@gmail.com
i have tried second method by removing the 3 chip resistor and connected external resistors but still there is no red light blowing on the chip
@Venkatesh Nakod I just simply replace the max30100 by max30102, same wiring diagram and it has worked. Not worth fixing it, such a waste of time.
