Keyes Microphone Sound Detection Sensor Module for Arduino


Elmwood Electronics has stopped accepting orders. This product might be available at PiShop.ca. Please check this blog post about our recent team merger.

This is a an economical sound detector. 

High sensitivity; The module has two outputs: AO, analog output, real-time output of the microphone voltage signal / DO, when the sound intensity reaches a threshold, the output high and low signal threshold - Sensitivity potentiometer adjustment.  5 volt input.

The DO (digital output) pin is HIGH by default. When sound is detected it is pulsed to LOW. Connect it directly to an Arduino without pull-up resistors.
