Sound Sensor LM386 Arduino Compatible
Would you like to have a sound detection for your project? Then this module is what you need. This sound sensor indicates if there is a sound that surpasses the threshold you have set. It is only checking if there is a sound, but it can't detect the type of sound heard, even the loudness of the sound, as well as the frequency. To adjust the threshold, you may rotate the on-board potentiometer. As this sensor is a digital one, it could only send HIGH(1) or LOW(signal) depending on the level of sound it hears. It can work with a 5v / 3.3V power supply. This module has the LM386 power amplifier and an electret microphone.
