Composition of automobile alarm system

A group of sensors, including switches, pressure sensors and motion detectors, can give out various alarms, from which a unique sound can be selected. The radio receiver controlled wirelessly by the key card and the spare battery can ensure the normal operation of the alarm system even when the main battery is disconnected. The computer control unit is also the "brain" of the alarm system, which can monitor the surrounding situation and give an alarm.

The "brain" of many advanced alarm systems is actually a small computer. When the sensor detects an abnormal situation, the "brain" will turn off the switch and activate the alarm device (that is, horn, headlight or alarm). Different security systems use different sensors, and the sensors are connected to the controller in different ways.
