Sensor Sound Detection LM393 Comparator

Description

This module uses a high-sensitivity electret microphone to capture sound waves. These sound waves are converted into an electrical signal and then processed by an onboard LM393 comparator.

The module features a potentiometer (the blue square with the screw head) that allows you to set a sound threshold. When the noise level in the room exceeds the threshold you’ve set, the module’s digital output (OUT) triggers, and the onboard indicator LED flashes.

Key Features

• Adjustable Sensitivity: The blue potentiometer can be turned clockwise or counter-clockwise to increase or decrease the sound level required to trigger the sensor.
• Dual Output Indicator: Includes a power LED and a signal LED that lights up when sound is detected
