Analog Sound Sensor Microphone Module | Adjustable Audio Detection Sensor for Arduino, ESP32, Raspberry Pi & DIY Electronics

The Analog Sound Sensor Microphone Module is a compact sound detection module designed to detect ambient sound levels and interface easily with microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, STM32, AVR, and PIC. Equipped with a high-sensitivity electret microphone and an onboard LM393 comparator, the module provides an analog output representing sound intensity and a digital output that triggers when the sound level exceeds an adjustable threshold.

An onboard potentiometer allows users to fine-tune the sensitivity according to the application. The module is ideal for clap switches, sound-activated lighting, noise monitoring, alarm systems, robotics, smart home automation, and educational electronics projects.
