Keyestudio KS0035

Microphone Sound Sensor with Potentiometer (Arduino-Compatible)

The keyestudio microphone sensor is typically used in detecting the loudness in ambient environment. The Arduino can collect its output signal by analog input interface. The S pin is analog output, that is voltage signal real-time output of microphone. The sensor comes with a potentiometer, so that you can turn it to adjust the signal gain. It also has a fixed hole so that you can mount the sensor on any other devices. You can use it to make some interactive works, such as a voice operated switch.

Specifications

• Operating voltage: 3.3V-5V (DC)
• Operating current: <10 mA
• Interface: 3-PIN
• Output signal: Analog

Sample Code

int sensorPin =A0 ; // define analog port A0 int value = 0; //set value to 0 void setup() { Serial.begin(9600); //set the baud rate to 9600 } void loop() { value = analogRead(sensorPin); //set the value as the value read from A0 Serial.println(value, DEC); //print the value and line wrap delay(200); //delay 0.2S }
