Sound Sensor Module – Microphone Detection for Arduino and Sound-Triggered Projects
The Sound Sensor Module detects audio signals and outputs either analog or digital signals based on ambient sound levels. It's perfect for creating sound-activated devices, clap switches, and noise-level monitors. Compatible with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms.
 
Key Features:
Microphone-Based Sound Detection
Captures environmental sound intensity using an onboard electret microphone.
Dual Output Options
Provides analog output proportional to sound intensity and digital HIGH/LOW output based on a user-set threshold.
Adjustable Sensitivity
Onboard potentiometer allows fine-tuning of the detection threshold.
Plug-and-Play Interface
Easy to integrate with development boards using standard VCC, GND, DO, and AO pins.
Onboard LED Indicators
Visual status LEDs indicate power and sound detection.
 
Applications:
Clap switches and sound-activated control
Voice-sensitive lighting systems
Ambient noise monitoring
DIY sound-reactive projects
Smart home automation triggers
