What it does

The Microphone Sound Sensor Module for Arduino & Raspberry Pi | Audio Detection Module detects ambient sound levels using an electret condenser microphone with onboard amplifier. It provides analog and digital outputs for audio-reactive and sound-activated projects.

Key features

  • Electret condenser microphone with onboard amplifier
  • Analog output proportional to sound intensity
  • Digital output with adjustable threshold
  • Onboard potentiometer for sensitivity adjustment
  • LED indicator for detection status
  • 3.3V-5V operation compatible with all microcontrollers
  • Compact module with easy interfacing

Good to know

  • Detects sound amplitude only – not suitable for frequency analysis
  • Ambient noise affects threshold setting – calibrate in target environment
  • Digital output triggers at adjustable threshold level
  • Not a high-fidelity microphone – for detection only
  • For frequency analysis, use MAX9814 + MSGEQ7 or FFT on Arduino
