Keyestudio Analog Sound Noise Sensor Detection Module for Arduino
The Keyestudio Analog Sound Noise Sensor is a compact module designed for Arduino and other 3.3V/5V microcontroller platforms, providing real-time analog voltage output proportional to ambient sound intensity for audio-reactive projects.
Features
- Real-time analog voltage output proportional to sound intensity.
- Onboard potentiometer for precise sensitivity adjustment.
- Wide 3.3V to 5V DC operating range with ultra-low current consumption (<10mA).
- Standard 3-pin interface (VCC, GND, AO) for easy connection to Arduino analog pins.
- Compact PCB with mounting hole for secure integration into projects.

The Keyestudio Analog Sound Noise Sensor Module integrates a high-sensitivity electret condenser microphone with a signal conditioning circuit to convert acoustic pressure waves into a corresponding analog voltage signal. This output varies in real-time with the amplitude of detected sound, making it suitable for sound level monitoring and audio-reactive control systems.
Designed for seamless integration with development boards like Arduino, ESP32, and Raspberry Pi, the module operates from a 3.3V to 5V DC supply. An onboard potentiometer allows fine-tuning of the microphone’s gain and the comparator’s threshold, enabling adaptation to different acoustic environments and project requirements.
