The LoRaWAN Control Terminal (868MHz) serves as a comprehensive Industrial IoT (IIoT) node, bridging the gap between actual field equipment and remote cloud platforms. This wireless controller, which operates on the 868MHz band (suited for Europe and other ITU Region 1 locations), streamlines complex telemetry projects by combining data gathering, logic processing, and device actuation into a single, DIN-rail mountable instrument. It is designed primarily for applications like as smart agriculture, building automation, and industrial monitoring, where dependable long-range connectivity and autonomous offline operation are required. This Remote Terminal Unit (RTU) provides a streamlined, cost-effective alternative to complex PLC and radio installations, enabling for rapid deployment in applications needing both sensing and control.
Stable Long-Range
Communication The wireless node, which is based on the standard LoRaWAN protocol, works seamlessly with both private gateways and public network infrastructure such as The Things Network (TTN). Using the 868MHz frequency, the gadget achieves deep signal penetration and long-range coverage. This connectivity provides consistent data transfer from remote places, such as agricultural parks or large industrial complexes, with transmission ranges of up to 4km in open environments, effectively eliminating the coverage constraints of typical Wi-Fi or cable cabling.
Hybrid Interface for Acquisition and Control
Unlike traditional sensors that simply transmit data, this IoT controller is equipped with a configurable interface array to handle both "Read" and "Write" activities.
Collection: The unit includes an RS485 interface for Modbus RTU sensors, a 0-10V analog input, and two optocoupler-isolated digital inputs. This enables the smooth integration of a variety of peripherals, including temperature transmitters, flow meters, and pressure sensors, without the need for additional adapters.
Control: The device's built-in Relay Output (24VDC/220VAC 3A) allows it to directly operate actuators. This functionality enables the system to turn on or off pumps, valves, alarms, or lighting systems based on received commands or local logic.
Edge Logic and Offline Autonomy
One distinguishing characteristic of this smart terminal is its capacity to execute control rules locally. Logical conditions can be set using a visual configuration interface (e.g., "If moisture < 20%, turn on relay"). This capability enables device linking and automatic alarm triggering without requiring constant cloud involvement. Crucially, the unit enables offline operation, which means that if the LoRaWAN network connection is broken, the controller will continue to execute its preset logic commands, guaranteeing that the local application's safety and stability are never compromised.
Seamless Integration with RS485 Sensors
This LoRaWAN Control Terminal is pre-validated with a diverse set of DFRobot industrial RS485 sensors, allowing you to quickly create complete monitoring systems.
- Smart Agriculture: Sensors for soil temperature and moisture, electrical conductivity, pH, and NPK.
- Weather Monitoring: Ultrasonic weather stations, wind speed/direction, and rain gauges.
- Water Quality: Dissolved oxygen sensors for freshwater and marine applications.
- Environmental: Solar Radiation, UV, and Ambient Light Sensors.
- Configuration Guide: For the entire list of compatible devices, default baud rates, and Modbus register maps, please refer to the Peripheral Device Recommendations.
