A sound sensor is defined as a module that detects sound waves through its intensity and converting it to electrical signals. sound sensor consists of an in-built capacitive microphone, peak detector and an amplifier (LM386, LM393, etc.) that’s highly sensitive to sound.
Sound sensors are used in many other days to day applications including Consumer electronics such as phones, computers, music systems, Security and Monitoring systems such as burglar alarms, door alarm, etc.
