I am using Nodemcu-32s with MAX30102 & MLX90614.

I noticed a thing that when I was working with both sensor individually then both of them were working fine but when I started them using together then both of them were not working.

After that, when I started using them individually again then I got "sensor not found" error.

I am not sure where I am making mistake.

I am connecting

MAX30102 Pins Nodemcu-32s Pins
Vin 5V
GND GND
SDA G21
SCL G22
MLX90614 Pins Nodemcu-32s Pins
Vin 5V
GND GND
SDA G21
SCL G22

I don't know what is making my sensors burnt out. Apart from this I am not aware how can I get accurate Pulse Rate & SpO2

I moved your topic to a more appropriate forum category @yash_7200.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.
