65dB Microphone Module

High-Sensitivity 65dB Acoustic Capsule: Outfitted with an electret condenser capsule tuned for precise sound wave sensing across high ambient noise and speech environments.

Dual Telemetry Signal Output (AO & DO): Features an Analog Output (AO) for continuous real-time sound amplitude waveform logging and a Digital Output (DO) for instant threshold switching.

Onboard Gain & Sensitivity Calibration: Features an integrated multi-turn potentiometer allowing fine-tuning of the trigger threshold and sound sensitivity to match room environments.

LM393 Voltage Comparator Core: Outfitted with an onboard LM393 comparator IC to deliver clean, noise-filtered digital switching logic with stable signal driving capability.

Integrated Power & Trigger LEDs: Equipped with onboard status LEDs to provide immediate visual confirmation of power connection and digital output activation during circuit testing.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with a top-mounted electret condenser microphone capsule, blue trimmer potentiometer, and tinned header pads.

Technical Specifications:

Operating Supply Voltage: 3.3V - 5.0V DC.

Sensitivity Rating: -65 dB.

Output Signal Types: Analog Voltage Output (AO) + Digital Switching Output (DO).

Color: Red PCB with Blue Potentiometer and Silver Microphone Capsule.

Usage Advice: Connect VCC (3.3V-5V) and GND to your microcontroller; route AO to an analog ADC pin for acoustic envelope monitoring or DO to a GPIO pin for voice/clap triggers.

Maintenance: Keep the microphone capsule aperture free of dust, flux residue, and liquids; wipe board surfaces gently using a soft, dry microfiber cloth.

Essential High-Sensitivity Acoustic Node: Position as an enhanced acoustic detection breakout board for sensitive decibel monitoring, voice-activated switches, room noise loggers, and robotics sound localization.

Highlight Dual Output Flexibility: Emphasize how dual analog waveform outputs and digital comparator threshold switching on a single compact board simplify integration across beginner and advanced projects.

Recommended Cross-Sell Add-ons: Pair with Microphone Sound Sensor Module, KY-037 Microphone Sound Sensor, XD-21 LM358 Amplifier Module 100x Gain Operational Amplifier, and ESD antistatic mat 50x40CM PCB Welding Mat.
