Small microphone module(SE019)

1.Introduction

This module is similar with the large microphone module(ST1146). The only

difference is the microphone, not only the size, but also the function. The large

microphone module has a electronic microphone, and the small microphone module

just has a normal microphone. The electret microphone has more high sensitivity, but

they share the same work method.

Specification

 Voltage:5V/3.3V

 there is a mounting screw hole 3mm

 the use 5v DC power supply

 with analog output

 there are threshold level output flip

 high sensitive microphone and high sensitivity.

 a power indicator light

 the comparator output is light

 Weight: 4g

 Frequency Response range:50Hz～20kHz

 Impedance：2.2K ohm

 Sensitivity：48~66dB

 polar pattern：Universal

 Operating temperature: -40 to 85 degrees celsius

 Operating humidity: 30~90%

 Storage temperature : -5 to 30 degrees celsius

 Storage humidity : 20~75%

 product size: 40*15*10mm

. Pinout Pin A0 G + D0 Description Analog signal output pin Ground Power(5V/3.3V) Digital signal output pin 3. Example We will use three example to show the different function of this module. Example 1 show you how to use the digital pin(D0), Example 2 show you how to use the digital pin(A0), In Example 3, we can try to combine this two function into one experiment. 3.

void setup () { pinMode (Led, OUTPUT) ;// define LED as output interface pinMode (buttonpin, INPUT) ;// output interface D0 is defined sensor } void loop () { val = digitalRead(buttonpin);// if (val == HIGH) // { digitalWrite (Led, HIGH); } else { digitalWrite (Led, LOW); } } ********Code End******** 3.2 Example 2 This example show you the Analog pin function, connect this module as below picture, and upload the code. Then open the Serial monitor, you can see some number between 0 to 1023.

********Code begin******** int sensorPin = A5; // select the input pin for the potentiometer void setup () { Serial.begin (9600); } void loop () { sensorValue = analogRead (sensorPin); delay (500); Serial.println (sensorValue, DEC); } ********Code End******** 3.3 Example 3 In this example we try to combine digital pin and analog pin together to control two LED lights, connection and code as below.
