Elecrow Item #: EL-SPM22101S -

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...

Sparkfun Item #: SEN-12642 -

"The SparkFun Sound Detector is a small and very easy to use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound, and an analog representation of its amplitude. The 3 outputs are simultaneous and independent, so you can use as many or as few as you want at once. The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted...
