A wireless door sensor is a smart security device that detects the opening or closing of a door and sends an alert to your smartphone or other connected devices via wireless communication. It typically consists of two parts: a sensor mounted on the door frame and a magnet attached to the door itself. When the door is opened and the magnet moves away from the sensor, it triggers the device to send a notification. Easy to install and integrate with your smart home system, a wireless door sensor provides added security by allowing you to monitor the status of your doors remotely, ensuring peace of mind when you're home or away.
