Car Sound Alarm System

This system is working according to the noise reflected from crashing windows and doors of the car or shaking the car hard when trying to steal it.

The microphones around the car will get that noise and make amplification for it and make the signal is readable and produce an alarm.

The circuit is demanding on a headphone that is changed electronically to be a microphone by reversing its function, also there is a microcontroller that is used to display output on LCD, display the condition of the system and activating the alarm.

This is a lab demo of the system

This is a module that to be reliable must implement more than one microphone to and connect all of them around the car as the park sensor.
