- 3D Stereoptic Sensors: To further expand the data gathered from the various clinics, the move to 3D-stereoptic sensors was used to provide not just occupancy status of exam rooms, but also the near real-time occupancy count data. Enhancing scalability, these sensors could monitor multiple rooms simultaneously, offering greater hardware efficiency.
Security and Connectivity:
-
- mmWave sensors utilized mTLS (mutual Transport Layer Security) for secure data transmission.
- Custom authorization for 3D-stereoptic sensors was implemented using AWS Lambda.
Data Aggregation and Storage:
-
- Data was streamed via Amazon Data Firehose and AWS IoT Core, stored in AWS S3, and processed through AWS Lambda.
- A centralized S3 data lake provided a secure, scalable repository for all processed data.
Visualization and Insights:
