Try the pad of the finger , not touching circuit just the sensor. block direct light by putting in a little box. The readings are way out. If you were at 80% SpO2 you would be passed out. 95 up is average depending on smoker/non smoker
good job! I got error of "max30105 was not found. please check wiring/power", checked online said reason of "RCWL design fault", how to fix? and I find the same board indicated MAX30102 by seller? thanks.
I'm not familiar with what "RCWL design fault" is but for the initial error, you probably have the connections mixed up. Please double-check them. The two versions can be used interchangeably but MAX30102 is the one primarily used for pulse sensing while the MAX30105 is used for smoke detection.
The sensor is a bit dependant on the pressure you give it from the finger. It is best if it is strapped to it fo an equal pressure at all times. Additionally, you can take several readings and average them out to provide a more stable output.
Thanks for posting. I knew that red and infrared light was used, but not green
I did not played with it but I think it's used for the air particles measuring.
@@TasteTheCodeOk, thanks for showing the code you used

Hi, why is the sensor reading always changing? Is it possible to adjust it, take the best reading and stop?

Isn’t max30105 for gas detection? thought you might be using mac30102? Correct me please if I’m wrong
Yes true but it can still detect the minute changes in skin color from the blood pulses.
Which of the two is more effective? MAX30102 and MAX30105
I have not worked with MAX30102 so I can't tell but I guess both get the job done relatively same.
Sir i am getting error like filters.h is not found what can i do now sir
You are missing that file. The code is available on my website: www.tastethecode.com/oximeter-monitor-with-oled-screen-and-max30105-sensor-on-nodemcu
hi, can you show us where to plug the jumper cables? thank you!
I already explain that in the video and you can figure out the wiring from the code as well as from the explanation in the written article.
Beats per minute... Not Bits
Hey, sorry, English is not my native language. I know that it is beats but I may have mispronounced that.
