LM393 Sound Detection Sensor Module

Description

LM393 Sound Detection Sensor Module

The Sound Detection Sensor Module is designed to detect ambient sound and changes in sound intensity. It incorporates a microphone, resistors, capacitor, potentiometer, LM393 comparator IC, and power and status LEDs. The module features a single-channel signal output and is compatible with Arduino, allowing easy integration into various projects. When a sound is detected, it outputs a low-level signal with high fidelity, and the signal light activates. This module also provides an analog output voltage that is directly proportional to the intensity of the ambient sound, which is ideal for more sensitive applications.
