ARDUINO COMPATIBLE MICROPHONE SOUND SENSOR MODULE

The keyestudio microphone sensor is typically used in detecting the loudness in ambient environment. The Arduino can collect its output signal by analog input interface. The S pin is analog output, that is voltage signal real-time output of microphone. The sensor comes with a potentiometer, so that you can turn it to adjust the signal gain. It also has a fixed hole so that you can mount the sensor on any other devices. You can use it to make some interactive works, such as a voice operated switch. Specification Operating voltage: 3.3V-5V（DC） Operating current: <10mA Interface：3PIN Output signal: Analog MOre information available at: KS0035 Microphone Sound Sensor with Potentiometer - Keyestudio Wiki
