Hi all, I’m new to raspberry pi and I was wondering if there is any sound sensor that can detect sound level in db? I want to make a mobile application that detect the number of db then provide some feedback. I’ve got a basic sound module but it’s only output high or low signal. ---

You’ll need something like this with an Arduino and read the values from the Arduino: > **[Gravity: Analog Sound Level Meter](https://core-electronics.com.au/gravity-analog-sound-level-meter.html)** > > This is an Arduino compatible sound level meter(also known as decibel meter, noise meter). It uses instrument circuit, low noise microphone, which make it accurately .. read more Or use a USB microphone and calibrate the sound level youself. I use a seperate sound level meter when using this method. You can use digital filters if you need to.
