SmartElex Sound Detection Sensor

SmartElex Sound Detection Sensor

The SmartElex Sound Detection Sensor is a compact and efficient sound sensor module designed to detect sound presence and measure sound intensity with precision. Built around the LM386 audio amplifier, it provides both analog (AOUT) and digital (DOUT) outputs, making it suitable for a wide range of applicationsfrom simple sound-triggered actions to detailed audio level monitoring.

Operating smoothly between 3.3V and 5.3V, this sound sensor Arduino compatible module integrates easily with popular development boards such as Arduino, STM32, and Raspberry Pi. Its low power consumption, small form factor, and included 4-pin cable make it perfect for sound-activated projects, noise detection systems, smart devices, and interactive electronics where reliable audio sensing is required.

Features:

• LM386 audio amplifier for a powerful sound signal enhancement.
• Detect low-level sounds with 200 amplification.
• Wide voltage range: 3.3 to 5.3 volts
• Dual outputs: analog (AOUT) and digital (DOUT).
• Low power consumption, suitable for embedded systems.
• Adjustable gain using external components
• Compact and lightweight; breadboard-friendly.
• Simple integration with Arduino, STM32, and more.
