Door and Window Sensors  

A door and window sensor is a sensor that can detect whether your door or window is open or closed. They often consist of two parts. One part is mounted on your door or window and contains a magnet. The other part is mounted next to it and can detect the magnet. When it detects the magnet, your door or window is closed and otherwise it is open.
