Description

✅

The Microphone Voice Sound Detection Sensor Breakout Board is a compact module designed to detect ambient sound levels using an onboard electret microphone. It outputs an analog voltage that varies with sound intensity, making it suitable for a wide range of sound-reactive electronics projects.

This module features a signal amplifier (typically LM393 or similar), allowing it to detect even relatively quiet sounds. It connects easily to Arduino, ESP32, Raspberry Pi, and other microcontrollers through a standard analog input pin.

Note: This module is designed for sound level detection, not for audio recording or frequency analysis.

🔧 Features:

• Electret condenser microphone

• Analog output signal proportional to sound intensity

• Operating voltage: 3.3V to 5V

• Onboard signal amplifier for increased sensitivity

• Compact PCB with mounting holes

• Easy to interface with most microcontrollers

⚙️ Pinout (Typically 3 Pins):

• VCC – Power supply (3.3V to 5V)

• GND – Ground

• OUT – Analog signal output

📦 Applications:

• Sound-activated lighting

• Clap-switch or voice-controlled projects

• Noise level monitoring

• Smart home and IoT audio triggers

• Educational electronics experiments
