CELORA W15 wireless SDI-12 unit
CELORA W15 by Delta-T is a compact wireless telemetry unit for building SDI-12 sensor networks and sending field data directly to the DeltaLINK-Cloud platform. It is designed for fast deployment in environmental monitoring, agriculture, horticulture, research and scientific applications.
The unit connects up to eight SDI-12 sensors and one event counter, transmitting data over 4G cellular connectivity. It also supports local logging on a memory card and mobile-app configuration through NFC, avoiding the need for a laptop in the field.
CELORA W15 is housed in an IP67 UV-stable polycarbonate enclosure. It can operate from internal battery or external power, integrates with Delta-T sensors such as PR2 and WET150, and can also work with compatible third-party SDI-12 sensors.
