What Are Car Alarm Sensors and How Do They Work?
Today’s sophisticated car alarm systems come with a variety of sensors, each tasked to do a very specific job. Door/hood/trunk sensors raise the alarm when a would-be thief opens a door, the trunk or the hood. Shock/impact sensors are used to detect the breaking of a window. Microphone sensors listen attentively, comparing the ambient sound level inside your vehicle to any spikes in that sound level, which might indicate that a break-in has taken place. Pressure sensors are set off when a change in air pressure (caused by a door opening or a window breaking) is detected. Tilt sensors monitor the angle of your vehicle to determine if it changes. If it does, it’s likely that the car has been hooked up to a thief’s tow truck. Proximity/perimeter sensors scan the area around your vehicle, looking for would-be thieves who might be lurking around your vehicle, perhaps peering through the windows, and planning their break-in.
Avtomobil signalizatsiya sensorlari nima va ular qanday ishlaydi?
Zamonaviy avtomobil signalizatsiya tizimlari turli xil sensorlar bilan jihozlangan bo'lib, ularning har biri o'ziga xos vazifani bajaradi. Bo'lajak o'g'ri eshikni, bagajni yoki kapotni ochganda, eshik/kaput/magistral datchiklari signalni ko'taradi. Zarba/zarba datchiklari oynaning sinishini aniqlash uchun ishlatiladi. Mikrofon datchiklari diqqat bilan tinglab, avtomobilingiz ichidagi atrofdagi tovush darajasini shu tovush darajasidagi har qanday ko'tarilishlar bilan taqqoslaydi, bu esa buzilish sodir bo'lganligini ko'rsatishi mumkin. Havo bosimining o'zgarishi (eshik ochilishi yoki oynaning sinishi natijasida) aniqlanganda bosim sezgichlari o'rnatiladi. Nishab sensorlari avtomobilingizning burchagini kuzatib boradi va uning o'zgarishini aniqlaydi. Agar shunday bo'lsa, mashina o'g'rining evakuatoriga ulangan bo'lishi mumkin. Yaqinlik/perimetr datchiklari avtomobilingiz atrofidagi hududni skanerlaydi, sizning avtomobilingiz atrofida yashirinib yuradigan, ehtimol derazalar orqali ko'zdan kechirayotgan va ularning kirib kelishini rejalashtirayotgan bo'lajak o'g'rilarni qidiradi.
