About this product
A sound detection module built around an electret condenser microphone (ECM). A comparator gives a digital high or low output when the sound level crosses a threshold set by its potentiometer, and an analog output follows the microphone signal. It is used in clap switches, noise alarms and simple sound-triggered Arduino projects.

How do I wire this module to an Arduino?
Connect VCC to 5V, GND to GND and DO to a digital input pin. Use the potentiometer to set the threshold at which the DO output changes state.
Can it measure sound level or only detect sound?
The DO pin is a simple on/off signal that shows whether the threshold was exceeded. For a level reading, use the AO analog output connected to an analog input pin.
