DIY Smart WiFi Oximeter using MAX30102 and ESP32

In this video we will show to how to build a Smart WiFi Oximeter that will sense and display Heart Rate + SP02 Values on a smartphone. We use MAX30102 sensor for sensing and the ESP32 for processing the transmitting the values to a smartphone!

Even After making all the connections correctly the led on the sensor is not glowing, does anyone have any idea why it is happening so?

Can this integrated into home assistant via esphome? Thx~

Hi Abhishek S,
Great project.

Before starting to copy this project I have following questions:

Q1: Because there is so little hardware needed does this project also work via a battery ?
Q2: If Yes which type of battery should that be then, could a 18650 battery do the job ?
Q3: Is a Whadda WPSE473 also a good Max30102 Pulsoxymeter ?

Thanks in advance.
Johan

What code could I use in an ESP32 TTGO T-Call v1.4 module to realize this oximeter project?

can i impliment this using esp 8266? mwith the code given in descriptioin

hi i keep getting error that ledc is not initialized? even though I followed exactly your provided codes. what would be issue here PLEASE HELPME

[Remiliascarlet-nw]

why my Blynk app looks different from the one in the vedio

[damselindisguise]

hi can i request for a written codes just to send the data to serial monitor?

[hynos]

Is it normal that I get this message from arduino : spo2_algorithm: No such file or directory ??

Were you truly at 95% sat... You wouldn't be feeling so good right now

after uploading the code, the device is being shown as offline on blynk
