With the Yealink RoomSensor, a wireless passive infrared (PIR) sensor, meeting rooms can be perfectly managed even over longer distances. The sensor not only sends information about whether a room is free or occupied, but also sends useful information regarding lighting conditions, room temperature as well as humidity. In combination with other devices, such as the Yealink Room Panel, the Yealink RoomSensor becomes an assistant for room occupancy planning. Via the "Internet of Things", the room sensor offers functions such as automatic check-in, lighting control, and room release.
