The LM393 Sound Detection Sensor Module for Arduino is designed to detect sound levels that exceed a specified threshold value. It utilizes a microphone to capture sound signals, which are then processed by an LM393 operational amplifier (op-amp). The desired sound level is adjustable using an onboard potentiometer. When the detected sound level surpasses the setpoint, an LED on the module illuminates, and the output signal is set to a low state.

Specifications and Features:

• Operating voltage: DC 3.3-5V
• Signal output indication
• Digital output signal
• Single-channel signal output
• Features a mounting hole for convenient installation
• The output signal goes low, and the signal light activates when sound is detected
