Milesight WS301 simply enables you to know when someone enters the office/building through door/window or something has been moved. The minimal magnet is placed inside the portable part, while the sensor is inside the fixed part that can be attached on door/window or other objects. With LoRa technology, one of the most low power consumption technologies, Milesight WS301 can work up to almost 2 years without bothering to replace battery. Compliant with Milesight LoRaWAN® gateway and Milesight Development Platform, WS301 will surely monitor the real-time open/close status and receive alarms. With a style of minimalism and compact size, the wire-free WS301 can be easily mounted on the doors, panes, or cabinets, greatly providing real applications for smart homes, smart office or smart factories.
