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!
Thanks
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~
why my Blynk app looks different from the one in the vedio
It’s still working in 2023?
can i impliment this using esp 8266? mwith the code given in descriptioin
Yes
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
Yes. You can run it from a battery. Simplest option is use an ESP32 Development Board that runs from a lithium ion battery. You can use this board - www.probots.co.in/esp32-development-board-lite-lolin32-wifi-ble-battery-charger.html
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
Check your connections, run I2C Scanner
Were you truly at 95% sat... You wouldn't be feeling so good right now
You are absolutely right. It is a DIY Smart WiFi Oximeter not Professional Medical Grade Oximeter.
Is it normal that I get this message from arduino : spo2_algorithm: No such file or directory ??
happens when library is not installed correctly. Try to install the library again.
after uploading the code , the device is being shown as offline on blynk
Blynk has released a new version. The high-level procedure is still the same. Modify code by using the inbuilt blynk example and documentation as reference.
What code could I use in an ESP32 TTGO T-Call v1.4 module to realize this oximeter project?
The code will be the same, you may have to customize the pin definitions
hi can i request for a written codes just to send the data to serial monitor?
Use the example under Sparkfun Library
hows the accuracy?
seems ok. Nice for evaluating what the MAX30102 sensor is capable of. But definitely not medical grade. Lots of improvements are required to make it medical grade like - sourcing original sensor ICs from Maxim, using professional designed PCBs and calibrating against a reputed oximeter. This project is the first step towards it.
