KY-038 Sound Sensor Module | Mic Board w/ LM393 | Analog & Digital Output | For Arduino/Raspberry Pi

No.MR-163
KY-038 Sound Sensor Module with LM393 comparator, analog/digital output, adjustable sensitivity. For Arduino/Raspberry Pi voice control projects.

Description

1. AO: Analog output, outputs the voltage signal of the microphone.

2. DO: Outputs high/low level signals when the sound intensity reaches a certain threshold.

[The threshold/sensitivity can be adjusted via the potentiometer.]

3. Operating voltage: 3–5V

4. Threshold-triggered level inversion output.
