sound sensor module provides an easy way to detect sound and is generally used for detecting sound intensity. This module can be used for security, switch, and monitoring applications. Its accuracy can be easily adjusted for the convenience of usage.Sound Detection Sensor Module for Arduino detects whether sound has exceeded a threshold value. The sound is detected via microphone and fed into an op-amp The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low It uses a microphone which supplies the input to an amplifier, peak detector and buffer. When the sensor detects a sound, it processes an output signal voltage which is sent to a microcontroller then performs necessary processing. This sensor can be used to build various electronic projects with the help of an Arduino board. which fundamentally gives your Arduino’s ears.
