[SOLVED] MAX30100 not working | Initializing pulse oximeter...FAILED | MAX30102 LED not working

#Max30100 sensor not working |

no red light on max30100 sensor after all connections & programming done |
if you are having a similar question in your mind or

" Initializing pulse oximeter...FAILED" |

"Initializing...
MAX30100 was not found. Please check the wiring/power"

if your serial monitor showing similar output and you are looking for the solution for these issues, then you have stumbled at the right place. this video will help you to solve all these issues.

So, take a deep breath and sit back and relax, we are going to solve all these issues in few minutes.

[truetalonator]

thank you sir, you have been infinitely more useful than any of my TAs or profs in solving this issue

[paragbharadia]

sir, what is the multimeter reading to look for at 04:03 before and after making cut can you tell sir please?

[aldijbi]

Thank you so much, it's work, i follow the cut method and jumper the internal resistor

[kiranns]

Can you post a schematic of the external resistor added on Breadboard? The video was not very clear. Thanks in advance.

[NicAqueous]

Worked perfectly after doing the first modification. Thank you!

[badrinarayans]

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"

[simtcr]

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

[saiachyuth]

After removing those 3 resistors and after making connection with external resistors, after that also No red light on max30100 sensor .tried with two max30100s but pulse oximeter is failed. can you please help me out this connection ?

[tobiadetula]

Would using a voltage divider on the SCL and SDA pins to essentially half the voltage of the I2C signal work?

[HLABS]

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.

[thinkbeyond]

Does this help, with calibration and accuracy as well?

[codingclub]

I followed this video as shown, but still not working
MAX30100 was not found. Please check the wiring/power.

[mumminenichaitanya]

I have removed the internal resistor and connected with external ressistor of 4.7 k ohms but still it is not working, Do u have any idea

[jayavarshini]

thankssss a tonnnn🥺 first method worked

[elcanaldelvince]

I have the black max30102, which resistors do I have to remove ?

[vamshidharreddy]

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.

[nurjamilahhaqimah]

I have tried the first method but why my sensor is getting overheat?

[pirithivi_]

Bro the red light glows....but it cannot read any signals....it shows 0 pulse and 0 spo2 on monitor

[ksucharithaksucharitha]

Sir, can the same method be used to solve the problem with MAX30102(the sensor is in black color)

[jungcookie]

Can you mention the External resistor type and watt
