A Door and Window Sensor is a small, wireless security device designed to detect the opening and closing of doors or windows. Typically consisting of two parts—a sensor and a magnet—these components are installed adjacent to each other on the door or window frame and the moving part itself. When the door or window is opened, the magnetic connection is broken, triggering the sensor to send an alert to a connected security system or smartphone app. This makes them an essential component in home and office security setups, helping to prevent unauthorized entry and providing real-time notifications. Many sensors can also be integrated with smart home systems to automate actions like turning on lights or activating alarms, offering enhanced safety and convenience.
