Adjustable Module with High-Sensitivity Microphone for Alarms and Voice Activation
The KY-037 module is a high-sensitivity sound detection sensor based on the popular LM393 comparator and an electret microphone. It is designed to capture changes in the sound environment, such as claps, voice commands, or noise, and convert them into an electrical signal. The module offers dual flexibility with an analog (AO) and a digital (DO) output – the analog output allows for measuring sound intensity, while the digital output provides a clear signal (HIGH/LOW) when a set threshold, adjustable via the built-in potentiometer, is exceeded. With an operating voltage of 3.3V – 5V and easy 4-pin connection (VCC, GND, AO, DO), it is ideal for projects with Arduino, Raspberry Pi, and other microcontrollers for purposes such as sound alarms, interactive installations, clap-activated devices, or noise monitoring systems.
Features:
- For sound detection module has two outputs:
- There is a mounting screw hole 3mm
- The use 5v DC power supply
- With analog output
- High sensitive microphone and high sensitivity
- A power indicator light
- The comparator output is light
Specifications:
int Led=13;//define LED interface
int buttonpin=3 //Define D0 Sensor Interface
int val;//define numeric variables val
void setup()
{pinMode(Led,OUTPUT);// Define LED as output interface
pinMode(buttonpin,INPUT);//Define D0 Sensor as output Interface }
void loop()
{val=digitalRead(buttonpin);//digital interface will be assigned a value of 3 to read val
if(val==HIGH)//When the light sensor detects a signal is interrupted, LED flashes
{digitalWrite(Led,HIGH)}
else
{digital Write(Led,LOW)}}
int sensorPin = A5; // select the input pin for the potentiometer
int ledPin = 13; // select the pin for the LED
int sensorValue = 0; // variable to store the value coming from the sensor
void setup() {pinMode(ledPin, OUTPUT);Serial.begin(9600);}
void loop()
{sensorValue = analogRead(sensorPin);
digitalWrite(ledPin, HIGH);
delay(sensorValue);
digitalWrite(ledPin, LOW);
delay(sensorValue);
Serial.println(sensorValue, DEC); }
