Introduction

This tiny MEMS microphone has an amplifier gain of 66. When there is no sound detected, it outputs voltage around 0.66*VCC. When speaking, you can easily get the acoustic waveform by ADC sampling. The module can be used on all kinds of 3.3V/5V main-controllers.

Sample Code - Read Data

Burn code, open the serial port plotter, it will display the acoustic waveform

void setup() {
  Serial.begin(115200);
}

void loop() {
  // read the value from the sensor:
  Serial.println(analogRead(A0));
  delay(10);
}
