Sound Sensor Module – Microphone Detection for Arduino and Voice-Activated Projects
The Sound Sensor Module is designed to detect ambient sound levels using a built-in microphone. It outputs both analog and digital signals, making it ideal for sound-activated switches, noise monitoring, and DIY interactive electronics. This module works perfectly with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms.
 
Key Features:
Built-in Electret Microphone
Captures sound intensity in the environment, suitable for real-time detection.
Analog & Digital Output
Analog output reflects sound volume; digital output triggers when sound exceeds set threshold.
Adjustable Sensitivity
Onboard potentiometer allows you to fine-tune the sound detection threshold.
Easy Integration
4-pin interface (VCC, GND, AO, DO) ensures plug-and-play compatibility with development boards.
LED Indicators
Onboard LEDs indicate power and digital output status for quick debugging.
 
Applications:
Clap switch circuits
Voice-activated devices
Sound-level alarms
Ambient sound-triggered lighting
DIY automation and robotics
