Today’s hot-desking office neighbourhoods provide employees with choices; on background noise, ambient light, and office environment. The IoT sensor provides feedback on each space’s utilisation and environmental conditions in realtime so employees can find a workplace that suits their individual needs.


Facility operations use the IoT sensor data via gateways or interfaces to track occupancy levels and environment mapping for building-use optimisation. Areas not being used can be placed into set-back mode to conserve energy.
