Seeed Studio 101020063 - Grove - Sound Sensor/ Noise Detector for Arduino

PRODUCT DETAILS

The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high-frequency signal that received from the microphone, and outputs a positive envelope. This will make for Arduino's signal acquisition. The output value depends on the level of the sound input. In order to avoid unnecessary signal disturbances, the input signal will go through two times filtering inside the module. Lastly, there is a screw potentiometer that enables manual adjustments to the output gain.

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