A WiFi door sensor is a smart security device designed to monitor the status of doors or windows by detecting whether they are open or closed. It typically consists of two parts: a sensor unit attached to the door frame and a magnet placed on the door itself. When the door opens and the magnetic contact is broken, the sensor sends an alert to your smartphone via WiFi, keeping you informed in real-time. Many WiFi door sensors integrate with smart home systems, allowing for voice control through platforms like Alexa or Google Assistant. These sensors are widely used to enhance home security, ensure doors are properly closed, and monitor access points in homes or offices.
