### 4. Functionality

The WZB-SMG02 operates as a wireless magnetic reed switch sensor within a ZigBee network. It detects the open or closed state of a door, window, or similar access point by monitoring the proximity between the sensor body and its magnetic counterpart. When the magnetic field is interrupted (e.g., when a door opens), the reed switch changes state, triggering a ZigBee signal transmission to the network coordinator or router.

How It Works:
1. The sensor is mounted on a stationary surface (e.g., door frame), and the magnet is placed on the moving part (e.g., door).
2. When the door or window is closed, the magnet keeps the reed switch in a closed state.
3. When the door or window opens, the magnetic field is broken, and the reed switch opens, sending a wireless signal to the ZigBee coordinator.
4. The coordinator or connected hub processes the signal and can trigger alerts, alarms, or automation routines (e.g., turning on lights, sending notifications).

Use Cases & Applications:
- Home security systems (door/window intrusion detection)
- Office and commercial building access monitoring
- Smart home automation (triggering lighting or HVAC systems)
- Industrial equipment enclosure monitoring
- Warehouse and storage area access control
