The WS301 simply informs you when someone enters or leaves the office/building through a door/window or when something is moved. The sensor is within the fixed component, which may be mounted to a door/window or other objects, while the minimal magnet is inside the portable portion. The WS301 can be readily installed on doors, windows, or cabinets, making it ideal for smart homes, offices, and factories.

The standard LoRaWAN protocol is used to transmit sensor data in real-time. LoRaWAN allows for encrypted radio broadcasts over vast distances with very minimal power consumption.
