Keyestudio Analog Sound Noise Sensor Detection Module for Arduino

The Keyestudio Analog Sound Noise Sensor Detection Module is a highly responsive microphone sensor designed to measure ambient sound levels in real time. Ideal for South African students, educators, and makers, this module allows you to easily integrate sound-reactive capabilities into your microcontroller projects.

Real-time ambient sound detection

This microphone sensor measures the loudness of the surrounding environment and outputs a real-time analog voltage signal via the S pin. Your Arduino can easily collect this output through its analog input interface for instant sound analysis.

Onboard potentiometer for gain control

The module features an integrated manual potentiometer, allowing you to easily adjust the signal gain. Simply turn the potentiometer to calibrate the sensor's sensitivity to suit your specific environmental conditions.

Convenient mounting hole

Designed with practical integration in mind, the board includes a pre-drilled fixed mounting hole. This allows you to securely attach the sensor to custom chassis, robotic frames, or interactive installations.

Ideal for interactive projects

With its rapid response, this sensor is perfect for creating voice-operated switches, sound-activated alarms, or interactive lighting displays. It offers an engaging way to teach students about sensor inputs and analog signals.

Flexible low-power operating voltage

Operating on a DC voltage range of 3.3V to 5V, this sensor is compatible with a wide variety of development boards. It features a simple 3-pin interface for quick, hassle-free wiring.
