HW-484 Sound Sensor Module

The HW-484 Sound Sensor Module is a compact and easy-to-use microphone-based sensor designed to detect sound and noise levels. It uses an onboard microphone and LM393 comparator to provide both analog and digital output signals, making it suitable for Arduino, ESP32, Raspberry Pi, and other microcontroller projects.

The onboard potentiometer allows you to adjust the sound detection threshold according to your application. The module provides AO (Analog Output) for sound-level sensing and DO (Digital Output) for detecting sound above the selected threshold.
