Industrial NB-IoT Controller for Smart Agriculture, Environmental Monitoring & Remote Telemetry
The Milesight UC502-N03GL is a rugged NB-IoT / LTE-M industrial controller designed for remote monitoring, data acquisition and control applications in outdoor environments. By leveraging cellular IoT networks, it enables direct cloud connectivity without requiring LoRaWAN® gateways or local wireless infrastructure.
Designed for demanding field deployments, the UC502-N03GL supports multiple industrial interfaces including RS232, RS485, SDI-12, GPIO and Analog Inputs, making it ideal for weather stations, irrigation systems, soil sensors, water quality monitoring, environmental stations, utility metering and industrial automation equipment.
The controller supports Modbus RTU communication, allowing seamless integration with a wide range of industrial instruments and sensors. Data can be transmitted directly to cloud platforms, SCADA systems and remote monitoring applications through NB-IoT or LTE-M cellular networks.
For long-term autonomous operation, the UC502-N03GL is powered by three replaceable ER26500 Li-SOCl₂ batteries with a total capacity of 27Ah, ensuring multi-year field operation. It also supports 5–24VDC external power input via an industrial M12 connector, providing flexibility for permanent installations.
Featuring an ultra-rugged IP68 enclosure, industrial M12 connectors, NFC configuration and support for Milesight DeviceHub and cloud platforms, the UC502-N03GL is a reliable solution for remote monitoring applications where gateway infrastructure is unavailable or impractical.
