Grove – Loudness Sensor
Detect sound with this well-engineered Grove loudness 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 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.
