This sound detection and microphone module provides both analogue and digital outputs for detecting sound with a microcontroller. The analogue output (AO) delivers a real-time voltage signal proportional to sound intensity, while the digital output (DO) triggers high or low based on an adjustable threshold set via the on-board potentiometer.

Compatible with Arduino and other 5V microcontrollers, it's a straightforward way to add sound detection or audio-level sensing to your project.

Key Features

  • Dual Output – Analogue (AO) for real-time audio level, digital (DO) for threshold detection
  • Adjustable Threshold – On-board potentiometer sets the digital trigger level
  • High-Sensitivity Microphone – Detects voice, claps, knocks, and ambient sound
  • Power Indicator LED – Shows when the module is powered
  • Comparator Output LED – Lights up when sound exceeds the set threshold
  • 3 mm Mounting Hole – Easy to secure in enclosures and projects
  • 5V DC Operation – Standard supply voltage for Arduino and similar boards

Ideal For

  • Sound-activated lighting and effects
  • Clap or knock detection switches
  • Noise-level monitoring
  • Arduino and micro:bit audio projects

The Sound Detection and Microphone Module appears in the following collections:
