When sound is detected, the module provides a digital output (DO) and an analog output (AO). The onboard potentiometer adjusts the detection sensitivity of the digital output only; it does not adjust the analog output.<\/p>\n<p>The source listing suggests using sound such as a voice or clap to trigger an action, for example switching a light. The actual trigger level depends on the adjustment and setup.<\/p>\n<ul>\n<li><strong>Supply voltage:<\/strong> 4\u20136 V<\/li>\n<li><strong>Outputs:<\/strong> digital DO and analog
