Detect sound strength with this well-engineered Grove sound sensor.
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 sound sensor. Using an electret mic and two-stage high-pass filter, it creates a nice detectable envelope signal for your Grove project. This sensor differs from the Grove Loudness Sensor by having a fixed output gain rather than an adjustable one using a potentiometer.
