Sound Sensor LM386 Arduino Compatible

Sound Sensor LM386 Arduino Compatible

The 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 that beyond the threshold. The threshold can be adjusted by the on-board potentiometer.

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

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

Application Idea

  • Sound controlled Lamp;
  • Sound monitoring


  • On-board LED indicator
  • Threshold adjustable
  • Working voltage: 3.3V-5V
