Security door sensors are devices that detect when a door or window is opened without authorization. They are typically used in conjunction with a home security system to alert the homeowner or monitoring service when a door or window is opened.


Door sensors are typically mounted on the door frame or windowsill, and they utilize a magnetic switch to detect when the door or window is opened. When the door or window is closed, the magnet is aligned with the sensor, and the circuit is complete. When the door or window is opened, the magnet moves away from the sensor, and the circuit is broken. This triggers the sensor to send a signal to the home security system, which then alerts the homeowner or monitoring service.
