The app connects directly with DeltaLINK-Cloud, creating an uninterrupted bridge between physical field hardware and the online platform while granting users complete authority over their data management.
DeltaLINK-Cloud Compatibility
The DeltaLINK-Cloud online platform serves as the perfect data management and visualization companion, offering a secure environment to store, organize, view, and graph the measurements in a variety of styles.
DeltaLINK-Cloud provides remote, instant access to data, along with real-time interaction with dynamic charts, not just static images.

Once active, measurements stream automatically to DeltaLINK-Cloud, minimizing the need for manual site visits and hands-on data retrieval.
Users can monitor live and historical data from anywhere using custom widgets and tailored dashboard layouts. To simplify tracking, data from multiple sensors or disparate field sites can be consolidated into a single report, offering a unified overview of environmental conditions across entire projects.
The platform also allows users to share data access with colleagues, download full datasets, and set up automated alerts that trigger the moment environmental thresholds are crossed.
Unlike generic telemetry gateways, Celora is purpose-built for DeltaLINK-Cloud. This tight integration allows Delta-T to deliver a fully supported, end-to-end system that encompasses hardware, cellular connectivity, secure data hosting, and continuous platform upgrades.
This comprehensive approach ensures reliable performance, provides a single point of contact for customer technical support across both hardware and cloud services, and features a transparent subscription model scaled to customer needs.
How Celora Works in the Field
Celora W15 units deploy into the field to gather data from an event counter and any SDI-12 sensor operating up to 12 V and 500 mA. The loggers run on an internal battery by default, but they also accept external power sources up to 16V.
A single Celora W15 unit manages up to eight SDI-12 sensors. Because it supports multi-parameter hardware, one unit can service up to eight complete SDI-12 weather stations simultaneously, delivering extensive, cost-effective environmental monitoring.
