Description
 
The Grove - Loudness Sensor is designed to detect the loudness of environmental sounds. Based on the LM2904 amplifier chip and a built-in microphone, it amplifies and filters the high frequency signal that is received from the microphone, and outputs a cleaner signal, making it easier for signal acquisition. The output value depends on the level of sound input. In order to avoid unnecessary signal disturbances, input signal will go through the filtering mechanism twice. Lastly, there is a screw potentiometer to adjust the output gain.



Features:
  • Grove compatible interface
  • Wide supply voltage range
  • Built-in signal filtering
  • Gain adjustable via screw potentiometer
