Dragino SDI-12 Sensor Interface (LoRaWAN, NB-IoT & LTE-M)

 

The Dragino SDI-12 Sensor Interface is designed to connect SDI-12 compliant environmental and agricultural sensors to LoRaWAN, NB-IoT, and LTE-M networks. It provides a practical solution for integrating weather stations, water monitoring sensors, and field-based instruments into modern IoT monitoring systems.

Support for SDI-12 Sensors SDI-12 is widely used across environmental monitoring, agriculture, hydrology, and meteorology. The Dragino SDI-12 interface enables reliable data collection from compatible sensors and transmits readings over long-range, low-power wireless networks suitable for both remote and fixed installations.

Multi-Network Connectivity The SDI-12 platform is available in LoRaWAN, NB-IoT, and LTE-M variants, allowing you to select the most appropriate network based on coverage, power requirements, and deployment environment. This makes it suitable for private networks as well as carrier-operated cellular networks.

Flexible Power Options Battery-powered and solar-powered models are available, supporting long-term unattended operation in outdoor environments where access to mains power is limited.

Enhanced Functionality with Telemetry2U When integrated with the Telemetry2U IoT platform, the SDI-12 Sensor Interface can be configured for dashboards, historical data logging, alerts, and device management. This enables clear visibility of sensor data and supports operational decision-making.
