LoRaWAN Soil Moisture & EC Sensor EU868 – Dragino SE01-LB

The Dragino SE01-LB measures three key soil values at one point: soil moisture, soil temperature, and electrical conductivity. It is built for agricultural and horticultural use where a single moisture reading is not enough and where operators need a more useful picture of actual soil condition. For irrigation, fertilization, and crop management, the combination of these three values is far more informative than moisture alone.

The sensor is intended for saline-alkali soils and loamy soils. Soil moisture is calculated using the FDR method with compensation from soil temperature and conductivity. It is also factory calibrated for mineral soil type. That makes it a practical fit for professional use in open-field cultivation, greenhouses, nurseries, orchards, vegetable production, and trial areas where soil response needs to be tracked over time.

In real deployments, the SE01-LB is used where irrigation decisions should not rely only on manual checks or visual judgement. Growers, irrigation planners, and system integrators use sensors like this to compare soil zones, reduce overwatering, monitor salt build-up in the root zone, and add soil temperature context to field data. It also fits research and demonstration plots where soil conditions need to be documented more consistently.

The LB version runs on an 8500 mAh Li/SOCl2 battery and is intended for long-term use at fixed sensing points. Bluetooth 5.1 helps with field setup, OTA updates reduce maintenance work, and LoRaWAN on EU868 fits distributed agricultural and environmental monitoring projects with small or large sensor rollouts.
