LM393 Sound Detection Sensor Module

LM393 Sound Detection Sensor Module

The LM393 Sound Detection Sensor Module for Arduino is designed to detect sound levels that exceed a predefined threshold value. Utilizing a microphone to capture sound, the module processes the input signal through an LM393 operational amplifier. Adjustment of the sound level setpoint is achieved through an onboard potentiometer, allowing users to customize sensitivity. Upon surpassing the set threshold, an LED indicator on the module illuminates, and the output signal is driven low, indicating the detection of sound beyond the specified level.
