LM393 Sound Detection Sensor Module

The LM393 Sound Detection Sensor Module is a highly sensitive audio detection module designed to detect sound intensity in the surrounding environment. It uses a microphone element combined with an LM393 comparator to convert sound vibrations into electrical signals. This module is commonly used in sound-activated systems, smart devices, and Arduino-based electronics projects.
