The Disruptive Technologies (DT) wireless Desk Occupancy Sensor makes unintrusive desk occupancy monitoring a reality. The tiny, easy to install sensor is placed exactly where needed and collects data to solve real operational challenges in Commercial Real Estate. The sensor uses a combination of temperature measurements and machine learning to determine if a desk is occupied or not. We achieve best-in-class battery life (eight years) because we utilize DT Silicon for the temperature measurement (low energy), the DT cloud service for running the machine learning algorithms (high performance), and DT Studio for dashboards, integrations, notifications, and more.
