I'm using Octopus Analog Noise Sound Sensor Detection Module (it's like a normal sound sensor without the potentiometer) in Arduino UNO programming with Arduino IDE. I want to get the value in decibels, but i can only get the analog value and I haven't been able to find any libraries... I also tried different programs where an operation is performed to convert the value, but the resulting decibels differ a lot from what it's supposed to be. If someone knows what can I do to get the db value from this sensor I would be very grateful.
Thanks in advance,
