Lesson 33 Sound Sensor
Introduction
The MIC Module is composed of a small microphone and an LM393 voltage comparator.
It can capture minor sound signals and convert them into electric ones. The threshold of
the comparator can be adjusted by the blue potentiometer on the module. This module
can be applied in sound alarm system.
