Sound Sensor Module

Description

The Sound Sensor Module for Arduino is designed to detect sound levels exceeding a threshold value. Equipped with a built-in microphone, The module incorporates an LM386 audio amplifier IC, providing an amplified analog waveform as the output. The module has a wide frequency range from 50 Hz to 13 kHz, making it capable of capturing a diverse spectrum of sound frequencies.

The module features an on-board potentiometer to adjust the sound level set point. When the sound level surpasses the set point, an LED on the module illuminates, and the output is sent low. By rotating the potentiometer clockwise, the amplitude increases, offering flexibility in sound intensity control
