DFRobot 868MHz & 915MHz LoRaWAN Control Terminals
DFRobot 868MHz and 915MHz LoRaWAN Control Terminals are optimized for regions using the EU868 band and are designed for industrial and agricultural IoT applications. The wireless controllers simplify complex telemetry projects by integrating data acquisition, logic processing, and device actuation into a single DIN-rail-mountable unit.
The DFRobot 868MHz and 915MHz LoRaWAN Control Terminals serve as comprehensive Industrial IoT (IIoT) nodes, bridging the gap between physical field devices and remote cloud platforms. The devices operate on the 868MHz band (suitable for Europe and other ITU Region 1 areas) or the 915MHz band. The Control Terminals are specifically engineered for scenarios such as smart agriculture, building automation, and industrial monitoring, where reliable long-range communication and autonomous offline operation are critical. By combining versatile interfaces with standard LoRaWAN connectivity, this Remote Terminal Unit (RTU) delivers a streamlined, cost-effective alternative to complex PLC and radio setups, enabling rapid deployment in environments that need both sensing and control.
