About this product

This module allows you to detect when sound has exceeded a set point you select. Sound is detected via a microphone and fed into an LM393 op amp. The sound level set point is adjusted via an on board potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low. It has working voltage of 3.3-5V.

The Microphone Sound Sensor Module is a simple microphone. Based on the power amplifier LM386 and the electret microphone, it can be used to detect whether there is any sound beyond the threshold. The threshold can be adjusted by the on-board potentiometer.

Adjust the on-board potentiometer to adjust the sensitivity. The module outputs HIHG/LOW when the voice is Lower/higher than the threshold set by the potentiometer.

Please note that this sensor can only output if there is sound that is beyond the threshold, but not the loudness and frequency.
