A wireless door sensor is a compact security device designed to detect the opening and closing of doors without the need for wired connections. It typically consists of two parts: a sensor and a magnet, which are installed on the door and its frame. When the door is opened or closed, the sensor triggers a wireless signal to a connected alarm system or smart home hub, alerting the user via notifications or activating alarms. Wireless door sensors are easy to install, highly versatile, and commonly used in home security systems to monitor entry points and enhance overall safety.
