Dragino

The Dragino SE0X-LB is a LoRaWAN Soil Moisture & EC Sensor designed for smart agriculture applications. It supports up to four sensor probes and is optimised for measuring soil moisture in saline-alkali and loamy soil types. Utilising Frequency Domain Reflectometry (FDR), it calculates soil moisture with compensation for temperature and electrical conductivity, ensuring accurate readings. Factory-calibrated for mineral soil, it delivers reliable performance in diverse environments.

This sensor measures soil moisture, temperature, and conductivity, wirelessly transmitting data to a LoRaWAN IoT server. Its LoRa technology enables ultra-long-range communication with minimal power consumption, offering strong interference immunity and reliable data transmission.

The SE0X-LB features BLE for easy configuration and supports over-the-air (OTA) updates, simplifying deployment and maintenance. Powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term operation, lasting several years in the field.

Each unit comes preloaded with unique LoRaWAN registration keys, allowing seamless integration with a LoRaWAN server for automatic connection upon activation.
