Wireless door/window sensors are smart devices that detect the opening or closing of doors and windows. They consist of two parts: a sensor and a magnetic strip. When the door or window opens, the magnet disconnects, triggering the sensor to send an alert to your smartphone or security system. These sensors are easy to install, battery-powered, and don't require wires. They help enhance home security by notifying you of unauthorized entries, giving you peace of mind whether you’re home or away
