I am working on a small project on sound detection of lungs.

I want to get the sound using a sound sensor and play it on a speaker in real-time using Arduino.

Please suggest to me a good sound sensor that can detect the sound of the lungs.

I have read on google that the best frequency for lungs is 100 to 600 Hz.

By the way, I am using Electret Microphone Amplifier - MAX4466 with Adjustable Gain

But it is not getting the values. I think I need a preamplifier.

Thank you for your help.

  • your question about a sensor is unrelated to the arduino, so it is off topic here – jsotola Jan 28 at 6:51

    Why would you go through an Arduino, if you just want to amplify the sound of the lung? Why not just hook up an amplifier and a speaker up to the microphone? The mic module, that you use, already has a preamplifier, so you only need one for the speaker. – chrisl Jan 28 at 8:00
  • You'd be hard pressed to get much lung sound with that little microphone. And what you think the Arduino would be doing in the mix is anyone's guess... – Majenko Jan 28 at 10:37
