Microphone Sound Detection Sensor 4Pin

Microphone Sound Detection Sensor 4Pin is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. Product description: sound sensor – microphone
The sound detector with a small electret microphone, a voltage supply range from 3.3 V to 5 V. The module is easy to use, has two outputs: an analog – to measure the intensity of the digital signal and changing state when exceeding a certain level.

Using sound sensor
The sensor has a 4-pin connector with analog and digital output A0 D0 to be attached to the pin of the microcontroller, e.g.an Arduino.
