Waveshare Sound Sensor Module ROHS - LM386 Amplifier, Digital/Analog Output
The Waveshare Sound Sensor Module is a compact audio detection board featuring an LM386 amplifier chip, providing both digital and analog outputs for sound presence and intensity measurement. It operates from 3.3V to 5.3V, making it compatible with Arduino, Raspberry Pi, STM32, and other 3.3V/5V logic development platforms.
Features
- LM386 Audio Amplifier Chip with up to 200x signal gain.
- Dual Output: Digital (DOUT) for threshold detection and Analog (AOUT) for intensity measurement.
- Wide Operating Voltage: 3.3V to 5.3V for flexible system integration.
- Low Power Consumption suitable for battery-powered and portable applications.
- Onboard indicator LED for visual confirmation of sound detection events.

The Waveshare Sound Sensor Module is an electret microphone-based detection system integrated with an LM386 low-voltage audio power amplifier. The module conditions the microphone’s output, providing both a clean analog voltage proportional to sound pressure level (AOUT) and a Schmitt-triggered digital signal (DOUT) that toggles when a user-adjustable threshold is exceeded. This dual-output architecture allows for simple presence detection or precise amplitude analysis.
Designed for low-voltage operation, the module is optimized for integration with common microcontrollers and single-board computers. The onboard potentiometer allows for fine-tuning of the detection sensitivity, while the compact form factor and standard pin header spacing facilitate rapid prototyping. Its robust signal conditioning makes it suitable for environments requiring reliable acoustic event monitoring.
