Circuitrocks Sound Sensor LM386 Arduino Compatible Projects for Raspberry Pi ESP32 STEM Robotics

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. We also have a MEMS version here.If you have somehow needed a decibel level, you can check this out.QUICK SPECS:LED indicatorAdjustable ThresholdWorking Voltage: 5V/3.3V
