Sound Sensor Module

Overview

The Sound Sensor Module is a compact and high-sensitivity audio detection module designed for a wide range of sound-activated projects. Equipped with an electret microphone and an LM393 comparator, this module accurately detects sound levels and converts them into both digital and analog signals. Whether you're building a clap-activated light, a voice-controlled robot, or a smart security system, this sensor provides a reliable and easy-to-integrate solution for your microcontroller projects.

Key Features

• High Sensitivity Electret Microphone: Captures ambient sound with precision.
• LM393 Comparator: Ensures stable and accurate sound level detection.
• Dual Outputs: Provides both digital (DO) and analog (AO) signals for flexible integration.
• Adjustable Sensitivity: Onboard potentiometer allows you to fine-tune the trigger threshold.
• Wide Voltage Compatibility: Operates from 3.3V to 5V DC, making it compatible with most microcontrollers.
• Compact Design: Small footprint (approx. 3.2cm x 1.7cm) fits easily into any project.
• Power and Signal LEDs: Visual indicators for power and sound detection status.
