Yealink RoomSensor Humidity Light Occupancy Temperature Wireless

Yealink RoomSensor is an enterprise-grade wireless Passive Infrared (PIR) sensor that monitors space occupancy, ambient light, temperature and humidity. It connects wirelessly via Bluetooth 5.0 and is powered by a CR123A lithium battery, offering a compact, cable-free solution for environmental monitoring in office and meeting-room environments. The sensor can be integrated with Yealink Workspace Management Platform and other compatible IoT devices to support intelligent space management and energy-saving strategies.

Advantages

The RoomSensor combines multiple sensing functions—occupancy detection, light level measurement, temperature and humidity monitoring—in a single device, reducing the need for separate sensors. Its Bluetooth 5.0 connectivity enables easy wireless deployment and association with IoT systems. The compact, battery-powered design (CR123A) simplifies installation without cabling and allows flexible placement. The device is compatible with Yealink Workspace Management Platform for centralized data and policy management.

How to use

Mount the RoomSensor on a wall or ceiling at the recommended location for coverage of the target area. Power the device with a CR123A battery and use Bluetooth pairing to associate the sensor with the local gateway, Yealink Workspace Management Platform or other compatible IoT controller. Configure sensing parameters and reporting intervals in the management platform according to your occupancy detection and environmental monitoring needs. Regularly check battery status and replace the CR123A cell when indicated.

Recommendations

Place the sensor to avoid direct sunlight and heating/cooling vents to ensure accurate temperature and humidity readings. For reliable occupancy detection, mount the sensor at a height and angle that cover the main activity area and minimize obstructions within the PIR field of view.
