Small Microphone Sound Sensor Module Overview
The Small Microphone Sound Sensor Module is a compact sound detection board featuring a high-sensitivity electric condenser microphone and an LM393 comparator. It offers both analog and digital outputs with adjustable threshold and onboard LEDs, making it ideal for audio level monitoring and sound-activated control in microcontroller projects.
Key Features of Small Microphone Sound Sensor Module
- Operates on 5V DC power supply with onboard power indicator LED
- High-sensitivity electric condenser microphone for accurate sound detection
- LM393 comparator provides a digital output with adjustable threshold via potentiometer
- Provides analog output (AO) for sound amplitude measurement
- Compact 35×14 mm PCB with a 3 mm mounting hole for easy installation
- Fast shipping from Zbotic and genuine module sourced from authorized distributors
Applications and Use Cases
- Voice-activated LED lighting and switch control in home automation
- Noise level monitoring and decibel threshold alerts
- Sound-controlled alarms or buzzer activation in security systems
- Interactive art installations responding to environmental sounds
- Arduino-based audio level meter and sound event logging
How to Use Small Microphone Sound Sensor Module
Connect VCC to a 5V supply and GND to ground, then wire the AO pin to your microcontroller’s analog input to read sound amplitude and the DO pin to a digital input to detect threshold crossings. Adjust the onboard potentiometer to set the desired sound level for the digital comparator. Mount the module using its 3 mm hole and use the LED indicators to verify power and digital output state.

Frequently Asked Questions
How do I adjust the sensitivity of this sound sensor module?
You can adjust the sensitivity by turning the onboard potentiometer. Rotate it clockwise to increase sensitivity (lower threshold) or counterclockwise to decrease sensitivity (higher threshold). Watch the comparator output LED toggle as you tweak the threshold.
What is the difference between the analog and digital outputs?
The analog output (AO) provides a voltage proportional to the detected sound amplitude, which you can read on an ADC channel. The digital output (DO) is generated by the LM393 comparator and switches state when the sound level exceeds the set threshold.
Can I use this module with Arduino or other microcontrollers?
Yes. The module runs on 5 V and connects directly to Arduino analog and digital pins. Simply wire VCC to 5 V, GND to ground, AO to an analog input for sound level monitoring, and DO to a digital input for threshold-triggered events.
