Window and door sensors are security devices designed to detect when a window or door is opened. They typically consist of two parts: a magnet and a sensor, which create a closed circuit when the window or door is shut. If the circuit is broken, such as when the window or door is opened, the sensor triggers an alert, notifying the security system or the homeowner of a potential breach.
