The Wireless Desk Occupancy Sensor uses a combination of temperature measurements and machine learning to determine if a desk is occupied or not based on temperature changes created by the presence of people sitting at a desk. The result is wirelessly transmitted to nearby Cloud Connectors (gateways) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the DT cloud infrastructure that users can either forward to other cloud services using Data Connectors or use the data directly in DT Studio (web application).
