LoRa Wireless Analog Bridge
WW-3C2M AA / WW-3C25 AA (Synchronization Mode)
The WW-3C2M AA / WW-3C25 AA is an industrial outdoor LoRa analog-to-analog gateway designed for long-range 4-20mA signal transmission. Ideal for remote water level monitoring, pump control, tank level sensing, SCADA integration, and industrial IoT automation, it delivers reliable performance across challenging field environments.
Long-Range Analog-to-Analog LoRa Gateway for Industrial Automation
The WW-3C2M AA and WW-3C25 AA provide a simple yet powerful solution to wirelessly extend analog signals over long distances using LoRa point-to-point communication (non-LoRaWAN). Designed for field environments such as smart water systems, remote pumping stations, agricultural irrigation, factory automation, oil tank monitoring, and utilities management, these gateways support 4-20mA and 0-20mA signal I/O for seamless integration with PLC, RTU, and SCADA systems.
With up to -137dBm sensitivity and 2W transmission power, the system ensures long-range, stable, and encrypted communication—ideal for replacing analog wiring in wide-area deployments. Built for demanding industrial use, it features IP68 waterproof protection, flame-retardant housing, and -40°C to 85°C operation, making it suitable for harsh outdoor environments.
For engineers who need reliable remote analog signal extension without the complexity of cellular or LoRaWAN networks, the WW-3C2M AA / WW-3C25 AA provides a ready-to-deploy, secure industrial link for SCADA, telemetry, and industrial control systems.
