A Wireless Door Sensor is a compact security device designed to detect when a door is opened or closed without the need for any wiring. It usually consists of two parts: a sensor and a magnet, which are installed on the door and its frame. When the door is opened, the sensor detects the separation from the magnet and sends a wireless alert to a connected security system or smartphone app. This makes wireless door sensors an essential component for home and business security, helping to monitor unauthorized entry in real-time. Their wireless design allows for easy installation and flexible placement, and they can often be integrated with other smart home devices to trigger alarms, lights, or notifications automatically.
