The Yealink RoomSensor is an enterprise-grade, multifunctional wireless sensor designed to support data-driven workspace management and environmental optimisation. Utilising passive infrared (PIR) technology, the Yealink RoomSensor detects room occupancy with high precision while also monitoring ambient light, temperature, and humidity. This compact, battery-powered device operates wirelessly via integrated Bluetooth 5.0, enabling easy deployment without physical cabling. Its compatibility with the Yealink Workspace Management Platform and other IoT ecosystems makes it a critical component in the modernisation of office environments, offering scalable deployment from huddle rooms to large meeting areas. In smaller rooms, a single Yealink RoomSensor ensures effective monitoring, while Bluetooth mesh networking allows multiple sensors to function collectively in larger spaces. With its adjustable lens and magnetic mounting design, the Yealink RoomSensor offers flexible installation options suited to varied room configurations. For organisations aiming to enhance operational efficiency, improve occupancy analytics, and reduce energy consumption, the Yealink RoomSensor provides a practical and scalable solution. It plays a vital role in enabling intelligent building management strategies, contributing to both workplace productivity and sustainability objectives.
