Product: LM393 Sound Detection Sensor Module Microphone Sensor

Function: Detects sound intensity using a built-in microphone and LM393 voltage comparator, converting audio signals into digital or analog outputs for sound-based automation.

Compatibility: Works seamlessly with Arduino, ESP32, ESP8266, Raspberry Pi, and other 3.3V–5V microcontrollers for sound-activated projects.

Construction: Equipped with a high-sensitivity electret microphone, LM393 chip, and onboard potentiometer for sensitivity adjustment; includes power and signal indicator LEDs.

Motion Control: Provides both analog (AO) output for continuous sound level monitoring and digital (DO) output for threshold-based sound detection.

Applications: Ideal for voice-activated systems, sound-reactive lighting, noise alarms, clapping switches, and smart automation projects.

Assembly: Simple 3-pin interface (VCC, GND, DO/AO) for easy wiring and direct breadboard or jumper wire connection; adjustable sensitivity via screw potentiometer.

Compact Design: Small, lightweight PCB with pre-soldered components for plug-and-play integration into embedded or educational electronics setups.
