Based on LM2904 amplifier and a built-in microphone， it amplifies and filters the high frequency signal that received from the microphone， and outputs a positive envelop. This is used for Arduino's signal acquisition. The output value depends on the level of sound input. In order to avoid unnecessary signal disturbances， input signal will go through two times' filtering inside the module. There is a screw potentiometer that enables manual adjustments to the output gain.SpecificationsVoltage :3.5~10 VDCWorking Frequency :50~2000 HzSensitivity : -48~66 dBSignal-to-noise Ratio : >58 dBOutput Signal range : Analog Signal (0-1023)Package List :5 X Grove - Loudness SensorDocument Link:http://wiki.seeed.cc/Grove-Loudness_Sensor/
