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 sensor will typically detect if a desk is occupied within 5-10 minutes of the person arriving at the desk. Similarly, it will typically detect if a desk is not occupied within 5-10 minutes of the person leaving.
The sensor wirelessly transmits the result to nearby Cloud Connectors (gateways) at a predetermined Heartbeat Interval (HBI) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data to the cloud via cellular or ethernet connectivity. From the cloud, the data can be integrated into other services using REST APIs and webhooks or viewed directly in DT Studio.
The Desk Occupancy sensor uses HBI to transmit a message notifying the system that it is present and operational. The sensor has a fixed Heartbeat Interval of 5 minutes.
This sensor comes in two versions: EU (Product No. 102553) and US (Product No. 102554), each tailored to meet distinct regional certifications, compliances, and wireless communication requirements.
