Description

Overview
  • Celora W15 wireless SDI-12 telemetry unit provides remote sensor connectivity and access to environmental monitoring data via DeltaLINK-Cloud.
  • Real-time cloud access to SDI-12 sensor measurements.
  • Connect up to 8 SDI-12 sensors plus 1 event counter per unit.
  • Direct integration with the DeltaLINK-Cloud platform for data storage, visualisation and reporting.
  • Manage data online with custom charts and dashboard widgets.
  • Local configuration via contactless NFC using the mobile app.
  • Cellular 4G connectivity for remote deployment.
  • Optional local micro-SD card logging for offline analysis.
  • Flexible power options: internal battery (included) or external supply up to 16 V.


Key capabilities
  • Fast deployment and simple ownership: field measurements are transmitted directly to DeltaLINK-Cloud.
  • Standards-compliant SDI-12 system (compatible with SDI-12 v1.3 or later) supporting third-party sensors.
  • Sequential SDI-12 mode supports up to 8 sensors and multi-parameter devices (e.g. SDI-12 weather stations).
  • Event counter input for devices such as tipping-bucket rain gauges.


Connectivity & configuration
  • 4G LTE / 2G GPRS modem with antenna (Nano SIM holder included).
  • Near-field communications (NFC, 13.56 MHz) for local configuration.
  • External connections via 2 x M12 and 1 x M8 glands (external power, SDI-12 bus and event counter).
  • Mobile app synchronises with DeltaLINK-Cloud for remote setup and management.


Data handling
  • Direct transmission of measurements to DeltaLINK-Cloud for live and historical access, custom charts, widgets and automated alerts.
  • Optional micro-SD memory card for local logging and offline file transfer to a PC.


Power & deployment
  • Default power: internal battery (8 x alkaline AA cells included).
  • External power supported up to 16 V (use appropriate cabling and supplies for temperature range).
  • Low power consumption: < 1.7 mA at 12 VDC.


Compliance & suitability
  • Weatherproof, compact enclosure for field deployment (IP67).
  • This W-15 version is suitable for Europe, Middle East & Africa.


Applications
  • Environmental monitoring, scientific research and agricultural/horticultural systems.
  • Soil moisture and health monitoring, meteorological data collection, hydrology, forestry and climate studies.


Technical specifications
  • Communications: 4G LTE / 2G GPRS modem + antenna (Nano SIM holder); NFC 13.56 MHz for local configuration.

  • Enclosure: White (RAL 9002), UV-stable polycarbonate; Ingress protection: IP67.
  • Dimensions: 120 mm x 120 mm x 60 mm (excluding glands and breather).
  • Weight: < 0.5 kg (excluding batteries, antenna, mounting brackets etc.).
  • Warranty: 2 years excluding batteries.
  • Accessories included: 8 x alkaline AA cells, antenna(s), memory card.
  • Optional accessories: SDI-12 network cable, SIM card, mounting kit, spare antenna, memory card, solar charging kit.
  • Compliance: CE including LVD, RED and RoHS 3.
  • Maximum cable lengths: SDI-12 cable (3-core DT-MI2) — 60 metres per sensor (max 480 metres); external power (2-core) — 3 metres max for external battery; event counter channel (2-core) — 6 metres max.
  • Notes: [1] 4G modem must be used with supplied antenna to maintain compliance. [2] Sensor current limited to <250 mA with specified internal AA cells. [3] Sensor current limited to <500 mA (thermal fuse) with external power. [4] Ensure selected power supply/batteries match the temperature range of intended application (specified alkaline batteries: -20 °C to +54 °C).
