"Sensor nodes," integrated into luminaires, continuously collect, store and communicate data on occupancy, luminaire performance and energy consumption. The motion sensor used in the sensor node is designed to be deployed in a layout with a high density of sensor nodes. Industry-standard building protocols enable easy integration into the smart building ecosystem. Similarly, data can be made available to Organic Response's cloud-hosted software platform, The OR Portal, where a data analysis engine can generate a deeper view of the workplace.
