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 changes in temperature created by the presence of people sitting at a desk.
A desk occupancy event with an OCCUPIED state is sent to the cloud when the desk becomes occupied. Similarly, a new event is sent to the cloud with a NOT_OCCUPIED state when a desk becomes available. 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 result is wirelessly transmitted to nearby Cloud Connectors (gateways) via the SecureDataShot™ protocol. Cloud Connectors relay sensor data into the DT cloud infrastructure. From here, the data can be forwarded to other cloud services using Data Connectors, viewed directly in DT Studio (web application), or sent to external services using webhooks or a REST API.
The machine learning model used to determine if a desk is occupied or not is trained based on data from a typical office environment (20-25C, 15-60% RN). While the sensor can be used in environments outside this range, the detection accuracy might be affected. DT continuously improves the machine learning model to cover a broader range of environments.
Continued research on biosensors is the way to ensure humanity stays ahead of time. Presenting the biosensors developed by the top 5 highest voted teams during SensUs Student Competition 2021.
Robot arms could become safer in industrial settings by applying an artificial skin containing proximity heat sensors to detect humans in all directions.
Using a highly-scalable approach to creating dense sensor networks, yet requiring only a pair of address lines, these researchers have taken inspiration from the human somatosensory system for a rapid-response sensitive sense of electronic touch.
