This post shows how to use the microphone sound sensor with the Arduino board.<\/p>\n

The Microphone Sound Sensor<\/h2>\n

The microphone sound sensor, as the name says, detects sound. It gives a measurement of how loud a sound is.<\/span><\/p>\n

There are a wide variety of these sensors. \u00a0<\/span>In the figure below you can see the most common used with the Arduino.<\/p>\n

\"sound-sensor\"<\/h2>\n

At the leftmost side,\u00a0you can see the KY-038 and at the right the LM393 microphone sound sensor.<\/p>\n

Both sensor\u00a0modules have a built-in potentiometer to adjust the sensitivity of the digital output pin.<\/p>\n

Where to buy?<\/h2>\n

You can go to Maker Advisor<\/a> and find the sensor’s best price.<\/p>\n
