Smart Alarm Module for Automobile Security System

A smart alarm module includes a connector terminal adapted to provide not more than five conductive paths from a fused box and an audio device of the vehicle to the smart alarm module, a CAN bus interface adapted to make connection to the CAN bus of the vehicle to detect communication protocol, a microcontroller adapted to arm the smart alarm module in response to the information received from the remote controller to provide the smart alarm module judgment operation based on the received information, a sensor adapted to quantized shock waves applied to the vehicle and to feed a first activating signal to the microprocessor when the quantized values exceeds a predetermined value, a power supply regulator providing power to the CAN bus interface, microprocessor, and sensor of the smart alarm module, and an output interface adapted to sound the audio device in response to output signal from the microprocessor.
