LM393 Sound Detection Sensor Module

Sound detection sensor module detects the intensity of sound where sound is detected via a microphone and fed into an LM393 op-amp. It comprises an onboard potentiometer to adjust the setpoint for sound level.

Sound Detection Sensor Module Pin Configuration

Pin Name	Description
VCC	The Vcc pin powers the module, typically with +5V
GND	Power Supply Ground
DO	Digital Output Pin. Directly connected to digital pin of Microcontroller
AO	Analog Output Pin. Directly connected to an analog pin of Microcontroller

Sound Detection Sensor Module Features & Specifications

Operating Voltage: 3.3V to 5V DC
LM393 comparator with threshold preset
PCB Size: 3.4cm * 1.6cm

About this project

This video shows how to use LM393 Sound Detection Sensor using Arduino. It also shows how you can control LED by clap with the help of Arduino and Sound Sensor. We have shown only to control LED, but by using the same concept you can control any electronic device.

LM393 Sound Detection Sensor Sound Sensor having 4 Pins:

AO – Analog Output

G – Ground

+ – VCC

DO – Digital Output

}

void loop() {

  int SensorData=digitalRead(soundSensor); 
  if(SensorData==1){

    if(LEDStatus==false){
        LEDStatus=true;
        digitalWrite(LED,HIGH);
