I need a sensor or sensor circuit that can determine the approximate loudness of a sound (which is in the range 30-80 dB). However, I cannot find any parts, schematics, or other helpful documentation on the internet. I have a microphone and AVR microcontrollers immediately available, so if anyone can recommend a solution involving solely those parts (and other common components such as resistors), it would be appreciated.
Thanks.
Thanks.
