Microphone Noise Decibel Sound Sensor Measurement Module 3p / 4p Interface
Tax included.
Features:
- This module can be connected to the analog I / O port,
- when speaking to the microphone, the analog value will be changed.
- A recorder can be made by reading and saving the analog value.
Specifications:
1const int ledPin = 13; // the number of the LED pin
2const int thresholdvalue=400; //The threshold to turn the led on
3void setup() {
4pinMode(ledPin, OUTPUT);
5}
6void loop() {
7 int sensorValue = analogRead(A0); //use A0 to read the electrical signal
8 if(sensorValue>thresholdvalue)
9digitalWrite(ledPin,HIGH); //if the value read from A0 is larger than 400,then light the LED
10 delay(200);
11 digitalWrite(ledPin,LOW);
