Dragino RS485 Sensor Interface (LoRaWAN, NB-IoT & LTE-M)

 

The Dragino RS485 Sensor Interface is designed to connect RS485 and Modbus sensors to long-range, low-power wireless networks using LoRaWAN, NB-IoT, or LTE-M. It provides a practical way to bring existing industrial and environmental sensors into modern cloud-based monitoring systems without replacing field hardware.

Multi-Network Connectivity This parent product covers multiple network variants, allowing you to select the most suitable connectivity option based on site conditions, coverage, and deployment requirements. LoRaWAN models are well suited to private gateways and long-range outdoor deployments, while NB-IoT and LTE-M variants support carrier-operated networks with strong penetration and wide-area coverage.

RS485 and Modbus Sensor Integration The RS485 interface is commonly used for Modbus RTU sensors, meters, and controllers. The Dragino RS485 device enables reliable data transmission from these sensors into cloud platforms for monitoring and analysis.

Flexible Power Options Battery-powered and solar-powered variants are available across the range, supporting low-maintenance operation in remote or unattended locations.

Enhanced Functionality with Telemetry2U Integration While the Dragino RS485 Sensor Interface can be connected to other platforms, Telemetry2U is the recommended option for customers seeking a supported, end-to-end monitoring solution. When combined with the Telemetry2U IoT platform, devices can be configured with dashboards, historical data logging, alerts, and device management tools.
