Product Overview: Wulian 43 Semi-Directional Motion Sensor
The Wulian 43 is an intelligent Passive Infrared (PIR) sensor that excels in corridor, entryway, and “perimeter-internal” monitoring. Operating on the ZigBee 3.0 protocol, it is designed to detect the heat signature of moving bodies within a specific directional beam. This “semi-directional” capability makes it ideal for triggering automations when someone enters a room, while preventing false triggers from pets or people walking past an open doorway.
