IoT solution door and window monitoring

Many sensors in building automation use reed contacts on windows and doors. The application of reed contacts is manifold. Their simple construction and reliability make them a popular choice for detecting opening and closing operations.

Window sensor = reed contact window?

Reed contacts are electromechanical switches based on the principle of magnetic fields. They consist of two magnetic contacts separated by a flexible metal strip. When a magnetic field is brought near the contact, the two magnetic contacts are attracted and close the circuit. Reed contacts are used in various applications, for example in door and window sensors.

Where are door and window sensors used in Smart Buildings?

  Energy management:  When a window is opened, the door or window sensor can detect this and inform the air conditioning system to adjust the cooling or heating output accordingly. This prevents energy from being wasted unnecessarily when windows are left open. A suitable practical example is the Smart Hotel soltution better.energy.

  Alarm systems:  Reed contacts on windows are also an essential part of alarm systems. They are placed on doors, windows and other potential entry points. If the contact is broken, for example by opening a door, an alarm signal is triggered indicating possible unauthorised activity.

  Industrial control systems:   Reed contacts are used in industrial control systems to monitor the status of machines and devices. For example, they can be used to monitor the opening or closing status of valves, shutters or circuits.

  Building automation:  In addition, door and window sensors can also be used to automate processes. For example, they are used in conjunction with lighting systems to turn on the light when a door is opened and turn it off when it is closed. This improves user-friendliness and helps save energy.
