ESP32 wireless electronic stethoscope
Budget: ₹1,500 – ₹12,500 INR
I’m looking to make a device., using the ESP32, that will use the INMP 441 MEMS I2S microphone (or similar) to detect sound.
I would like the sound to be transmitted via ESPNOW to a receiver where it will be output to an I2S DAC such as the PCM5102. Something I can use with headphones.
Sound can be MONO with medium quality. 16bit?? 8bit??
Transmitter:
ESP32
I2S microphone (INMP 441 or similar)
Transmit via ESPNOW
Receiver:
ESP32
I2S DAC (PCM5102 or similar)
Receive via ESPNOW
After this is complete and working, I will use this to test the abilities of the microphone to detect some specific sounds I’m looking for.
This will lead to further development of the transmit / receive system as well as one more control function.
