How do door and window sensors work? -When the security system is armed, the sensors communicate with the central hub or control panel by reporting the door or window is secure. If the door or window is opened, the circuit is broken, and the control panel interprets this as a security breach.

Window sensors are simple magnet mechanisms that send up alerts if one of your windows is opened while your security system is armed. Today, all of the best home security systems will come with window and door sensors to make sure your home will be secure.

Door sensors are devices that let you know when someone has opened a door. Most are a type of contact sensor that uses a reed switch and magnet. When the door is closed, the magnet keeps the reed switch circuit closed.

The window sensor has a torsion spring, an energy-generating component and a radio micro-controller. Those are its three main parts. This is how it works: When the sash is closed or opened, a torsion spring is activated and actuates the power generator, operating on the principle of electromagnetic induction.

Door and window sensors are contact sensors composed of two main parts that are a magnet and a sensor. This is also called a magnetic switch. The magnet itself is generally placed on the door, while the sensor is installed on the door frame.

In general, there are three main types of window sensors - contact sensors, glass break sensors, and motion sensors - although there are variations within those three categories.

Contact sensors consist of a magnet and a sensor. When a door or window opens, the sensor's magnetic field breaks. This break flips a switch in the sensor. The sensor transmits this information to the alarm panel, which then alerts you. This type of magnetically operated sensor is known as a reed switch.

Optical Sensors or Motion Detectors These types of sensors are the most modern and popular and are used the most. They are usually installed at either the tops of the sides of the doors and can detect movement. The motion of someone or something moving will trigger the doors to open.

There are many different types of sensors, the main categories are;

• Position Sensors.
• Pressure Sensors.
• Temperature Sensors.
• Force Sensors.
• Vibration Sensors.
• Piezo Sensors.
• Fluid Property Sensors.
• Humidity Sensors.

There are two types of sensors: Direct Sensor: A sensor that can convert a non-electrical stimulus into an electrical signal with intermediate stages. Eg: thermocouple (temperature to voltage). Indirect Sensor: A sensor that multiple conversion steps to transform the measured signal into an electrical signal.

A contact sensor is a two-part device comprised of 1) a reed switch, a simple electrical switch controlled by a magnetic field and 2) a magnet. The reed switch is mounted on the frame of the door or window, and the magnet is mounted on the moving part of the door or window.

Contact sensors are security devices typically installed on doors and windows. They can notify you and your system in the event a door, window, or gate opens, or send an alert during an intrusion.

Types of Sensors/Detectors/Transducers Sensor types are common among many of the various subcategories. For example, Hall effect sensors are found in proximity sensors, level sensors, motion sensors, and so on. Infrared sensors are used for level sensing, flame detection, etc.

All types of sensors can be basically classified into analog sensors and digital sensors. But, there are a few types of sensors such as temperature sensors, IR sensors, ultrasonic sensors, pressure sensors, proximity sensors, and touch sensors are frequently used in most electronics applications.

These sensors are used in automotive, aerospace, medical, defence and industrial applications. In automotive systems these are widely used in oil pressure sensor, crash detection, fuel-tank vapour pressure monitoring, exhaust gas recirculation, engine management system, etc.
