Analog Sound Sensor Microphone Module | Compoden
Analog Sound Sensor Microphone Module
The Analog Sound Sensor Microphone Module captures environmental sound and converts it into a proportional analog voltage. It uses an onboard electret microphone and amplifier, outputting a continuous signal ideal for real-time sound level monitoring. With a built-in sensitivity adjustment, you can fine-tune the response for whisper‑quiet or loud environments.

- Voice clap detection for home automation
- Ambient sound level monitor with serial output
- Simple music-reactive LED visualizer
Compatibility
Works with any microcontroller that has an analog input: Arduino Uno, Nano, Mega, ESP8266, ESP32, Raspberry Pi Pico (with ADC), and STM32. Connect VCC to 3.3V or 5V, GND to ground, and OUT to an analog pin. Logic levels match both 3.3V and 5V systems without extra level shifting.
Wiring Notes
Connect the VCC pin to a 3.3V or 5V power rail, GND to ground, and the OUT pin directly to an analog input on your board. The analog voltage ranges from 0V in silence to nearly VCC for loud sounds. Start with the potentiometer at mid‑range; turn it to adjust output gain up or down depending on ambient noise. Avoid powering the module from a digital I/O pin that cannot supply sufficient current.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, directly. Connect VCC to 5V, GND to GND, and OUT to any analog pin (e.g., A0). Read the analog value with analogRead().
Can I detect specific sound frequencies with this module?
The analog output represents overall sound amplitude only. To detect specific frequencies you would need a microphone module with digital I2S output and perform Fast Fourier Transform (FFT) analysis in code.
How do I adjust the sensitivity?
Locate the small blue potentiometer on the board. Turn it clockwise to increase output gain (more sensitive) or counterclockwise to reduce it. Adjust while monitoring the analog reading for your target noise level.
