5 High Sensitivity Microphones with 10mm x 6.5mm Diameter

Description

What it is

High-performance microphone sets of 5 with a diameter of 10mm*6.5mm are ideal for Arduino projects and audio and voice applications.

Features

• Diameter: 10mm x height: 6.5mm

What it is for

The microphones are useful for projects that require clear and sensitive audio recording, such as home alarm systems or other audio applications.

Tutorial: How to Use High Sensitivity Microphone

This 10mm diameter microphone is ideal for projects that require clear and sensitive audio recording. It is suitable for both beginners and more experienced makers.

What you need

• Arduino Uno or compatible
• JST connection (if required)
• Connection cable
• Arduino IDE software installed

Steps

1. Connect the microphone to the analog pin A0 of the Arduino.
2. Check the microphone’s operating voltage on the datasheet and connect it to +5V or 3.3V of the Arduino.
3. Connect the GND of the microphone to the GND of the Arduino.
4. Open Arduino IDE and upload a simple sketch to read analog values from pin A0.
5. Monitor the Arduino serial console to see the input values.
6. Test the microphone sensitivity by performing a sound test.
7. Adjust the volume or audio input as needed.
8. Further test with more complex projects such as voice recognition or audio recording.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  int val = analogRead(A0);
  Serial.println(val);
}

Mini project

Create a home security system that activates an alarm or sends a message when it detects sounds above a certain level.

Common mistakes

• Connect the microphone to an incompatible voltage with Arduino.
• Do not check the polarity of the microphone before installation.
• Use inadequate connections that cause interference or noise in the audio data.
• Omit testing the microphone to ensure its proper function.

Recommended accessories

• Audio Amplifier
• Wi-Fi Module to send audio data online
• 3D printing to create a protective container for the microphone.
• LiPo battery for portable power supply

Frequently asked questions

Does the microphone work outdoors as well?
Yes, but an acoustic shield or environmental noise protection might be necessary.

Can I connect multiple microphones together?
Yes, with the help of a multiplexer or by splitting the Arduino’s analog inputs among several microphones.
