Sound Sensor Module

Product Description

The Sound Sensor Module is a compact and easy-to-use sound detection sensor designed for Arduino, Raspberry Pi, ESP8266, ESP32, and other microcontroller projects. It can detect sound intensity from the surrounding environment and convert it into digital or analog signals for further processing.

Equipped with a high-sensitivity microphone and onboard signal processing circuit, this module is ideal for sound-activated projects such as clap switches, noise monitoring systems, security alarms, voice-controlled devices, and smart automation applications.

The adjustable sensitivity potentiometer allows users to fine-tune the detection threshold according to their project requirements. Its simple interface and reliable performance make it suitable for both beginners and advanced electronics enthusiasts.
