hi, I need help to design a sound measure with Arduino and getting the data with db. Can anyone help
You can use any Arduino-compatible microphone sensor module.
Connect it to any analog pin of Arduino, and use the analogRead(pin number) command.
It’ll give you a value b/w 0 to 1023, now convert this value to decibels. I’m not sure as to what relation should be used. Decibels are generally calculated as 10log(Intensity wrt reference). You may figure that out.
