Sound Detection using BigSound Sensor

 Sound Detection using BigSound Sensor

Just Arduino Things | TW TechieTube

Detect a Sound near surroundings and Make an LED Glow system.



Principle:

Big Sound Sensor is a module that detects sound and its intensity. You can select a point of sound intensity and detect sound when it exceeds a set point. In a loudspeaker, electricity flows into a coil of metal wire wrapped around (or in front of) a permanent magnet. The changing pattern of electricity in the coil creates a magnetic field all around it that pushes against the field the permanent magnet creates.

Components Required:

  • Arduino UNO                 (1)                        
  • Big Sound Sensor           (1)
  • Breadboard                     (As per Requirement)
  • Jumper Cables                (As per Requirement)
  • Arduino Bus Cable         (1)

Construction:

A Simple project to detect Human or Animal Interaction using the Passive IR Sensor.




Now connect the Sensors pins with the order given,

Vcc  - Arduino 5v/3.3v Pin
Gnd  - Arduino Gnd Pin
AO   - Any ANlog Pins from A0 to A5 
(OR)
DO   - Any Digital Pins except D1/D2 on UNO.
Incl.  an LED in D13 and Gnd for external value. 

As explained in the Video, the Code is written as Follows.

Code:

//ARDUINO BIGSOUND SENSOR
  //DEFINE THE VARIABLES
const int led=13;
const int sound=A0;
const int threshold=200; //Threshold value for sound sensor
int sousen;
void setup() 
{
Serial.begin(9600);
pinMode(sound,INPUT);
pinMode(led,OUTPUT);
}
void loop() 
{
sousen = analogRead(sound);
if (sousen>=threshold)
    {
    digitalWrite(led,HIGH);
    delay(1000);
    }
else
    digitalWrite(led,LOW);
}
