Microphone Sound Sensor Module

The Microphone Sound Sensor Module is a high-sensitivity sound detection component designed for a variety of electronic and prototyping applications. It provides two distinct output signals for maximum flexibility in your projects. The analogue output delivers a real-time voltage signal that corresponds directly to the microphone's input, ideal for measuring sound levels or creating audio-reactive systems. The digital output provides a clean on/off signal, activating when the detected sound surpasses a user-adjustable intensity threshold.

This compact module is engineered for reliable performance across a wide operational range. It features convenient LED indicators for power status and comparator output, allowing for immediate visual feedback during setup and use. With a high sensitivity range from 48dB to 66dB and a broad frequency response of 50Hz to 20kHz, it can accurately detect a wide spectrum of audible sounds.

The module is designed for easy integration, operating on a common DC voltage range of 3.3V to 5V, making it compatible with popular development boards like Arduino, Raspberry Pi, and other microcontroller systems. Its robust design includes a 3mm screw hole for secure mounting in your enclosures or projects.
