Car door sensors are a safety “must-have” these days. With car insurance prices constantly rising and car thefts still commonplace, protecting your vehicle from theft and other security risks is important.
Car door sensors are a great way to secure your car against theft.
Why do you need a Car Door Sensor that Sends Text Messages?
New research shows that vehicles in the US. are being targeted by thieves more than ever.
It is estimated that more than 2 million vehicles are stolen in the US each year, more than the number of homes robbed.
Consider a car door sensor that sends a text message to keep your vehicle safe.
The sensor installs on your car door and sends a text message to your phone or email when your car door is opened.

How does a car door sensor work?
Your car’s electrical system is the main driver behind your car’s door sensors.
There are several wires and sensors in your vehicle within this system, starting with the car battery.
The battery supplies power to a junction box equipped with fuses and switches.
From the junction box, a wire runs to each sensor system. Each sensor system consists of detecting whether the circuit is open or closed, depending on the function of the signal. For example, car door sensors are part of the same system.
A wire runs from the box to different parts of your car depending on what your car needs to signal.
For example, the driver’s door may have different sensors and signals for locked doors, unlocked doors, doors with child locks, doors ajar, or rolled down windows.
Almost all door and window sensors use a “reed switch” to determine when a protected area has been breached.
Invented in 1936 at Bell Telephone Laboratories, reed switches are used everywhere from pedal keyboards to laptops (ever wonder how your computer manages to go to sleep when you close the lid? That’s a reed switch that works!).
A reed switch consists of a series of electrical connections that are slightly spaced apart. When a magnetic field is applied parallel to the electrical terminals, it pulls them together and closes the circuit.
Door sensors have a reed switch and a magnet, creating a closed circuit. When someone opens a guarded door or window, the magnet is pulled away from the switch, breaking the circuit and triggering an event.
Depending on your installation and your system’s mode, this can be a discrete text, a chime alarm, or a full alarm.
Gone, however, are the days when you had to rely on wire sensors to protect your car from theft. Instead, there are portable car door sensors that can easily send you phone alerts and emails whenever your car door is opened without your knowledge.
