Big Sound Sensor


The 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
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.
