Detect sound with this well-engineered Grove loudness sensor.


Description [Hide]

Detecting sound isn't as simple as a mic into an input. Signal conditioning and gain control are important, and are incorporated into this Grove Loudness sensor. Using an electret mic and two-stage high-pass filter using an LM2904 opamp, it creates a nice, detectable envelope signal for your Grove project. Output gain is also configurable via a built-in trim potentiometer.

Specifications:

  • Grove-compatible interface (analog)
  • Adjustable output gain
  • 3.5 ~ 10VDC
  • 50-20kHz mic frequency sensitivity
  • -48 ~ 66 dB mic sensitivity
  • >58db SNR ratio
