Dragino SE02 Dual Soil Moisture & EC Sensor (LoRaWAN, NB-IoT & LTE-M)

 

The Dragino SE02 Dual Soil Moisture and EC Sensor is designed for monitoring soil conditions across multiple points using a single device. With two connected soil probes, it enables comparison of moisture levels and electrical conductivity between different soil zones, depths, or crop rows, supporting more informed irrigation and soil management decisions.

Multi-Point Soil Monitoring The SE02 supports two simultaneous soil measurements, making it ideal for applications where comparative data is required. This includes monitoring different soil depths, adjacent growing areas, or zones with varying irrigation or soil composition.

Flexible Network Deployment The SE02 is available in LoRaWAN, NB-IoT, and LTE-M variants, allowing deployment across private LoRaWAN networks or carrier-operated cellular networks depending on site coverage and operational requirements.

Designed for Long-Term Outdoor Use Battery-powered and solar-powered variants support long-term unattended operation, making the SE02 suitable for farms, remote field installations, and environmental monitoring locations.

Enhanced Functionality with Telemetry2U Integration When integrated with the Telemetry2U IoT platform, the SE02 provides dashboards, alerts, historical data logging, and device management tools. This enables users to track soil variability over time and respond proactively to changing conditions.
