Under what circumstances will the car alarm go off?

External force knocking, violent car smashing, pulling the car door, unauthorized entry into the car without deactivating the alarm, firecrackers going off, and vibrations from large vehicles passing by can all trigger the car alarm. Additional information about car alarms is as follows: 1. Working principle: When the sensor is struck or shaken, causing it to vibrate, a small ball inside begins to roll. As it rolls away from a smaller secondary electrical contact, the circuit formed by this secondary contact and the central electrical contact is broken. At this point, the switch opens, signaling the controller that the ball has moved. As the ball continues to roll past other secondary electrical contacts, the circuit repeatedly closes and opens until the ball finally stops rolling. 2. System composition: The most basic car alarm system consists of one or more sensors connected to an alarm. The simplest alarm system involves installing a switch on the driver's side door and connecting it with wires. If someone opens the door, the alarm will sound. Installing such a car alarm system requires a switch, some wires, and an alarm. Most car alarm systems are more complex than this. These systems include a set of sensors, including switches, pressure sensors, and motion detectors.
