A Wi-Fi door magnetic sensor is a security device that detects when a door or window is opened or closed by using a magnetic field. The sensor is typically composed of two parts: a magnet and a switch. The magnet is placed on the door or window, while the switch is mounted on the frame. When the door or window is closed, the magnet aligns with the switch, keeping the sensor inactive. However, if the door or window is opened, the magnet moves away from the switch, triggering the sensor and sending an alert to the user's smartphone via Wi-Fi. These sensors are easy to install and provide real-time notifications, offering a convenient and efficient way to monitor entry points. Many Wi-Fi door magnetic sensors can be integrated with smart home systems, allowing for additional automation, such as activating cameras, lights, or alarms when the sensor is triggered. This makes them a valuable tool for home security and protection.
