Mikrofonzaj decibel hangérzékelő mérőmodul 3p / 4p interfész az Arduino számára
Microphone Noise Decibel Sound Sensor Measurement Module 3p / 4p Interface for Arduino
Description:
Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.
Specifications:
PCB size 33.0mm X 14.0mm X 1.6mm
Working voltage 5V DC
Operating voltage 5V DC
Compatible interfaces 2.54 3-pin interface and 4-pin Grove interface(1)
Note 1: S for digital output port, N for not used pin, V and G for voltage at the common collector and ground respectively. When there is no operation, digital output is VDD; when the button is pressed down, the digital output is 0V.
Electrical characteristics:

DEMO:
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);
