Microphone Sound Sensor Module for Arduino & Raspberry Pi | Audio Detection Module

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

Technical Specifications

Applications

• Sound level detection and noise monitoring
• Clap switches and sound-activated control
• Audio-reactive lighting and LED effects
• Security alarms with sound triggers
• Voice activation prototypes
• Simple audio spectrum projects

Important Notes

• 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
