It has working voltage of 3.3-5V.

Microphone Sound Sensor Module

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.
