Dragino SE0X-LS – LoRaWAN Soil Moisture & EC Sensor Transmitter

The Dragino SE0X-LS is a LoRaWAN Soil Moisture & EC Sensor for IoT of Agriculture which can be equipped with 4 sensor probes. It is designed to measure the soil moisture of saline-alkali soil and loamy soil. The soil sensor uses FDR method to calculate the soil moisture with the compensation from soil temperature and conductivity. It also has been calibrated in factory for Mineral soil type.

It detects Soil Moisture, Soil Temperature and Soil Conductivity, and uploads the value via wireless to LoRaWAN IoT Server.

The LoRa wireless technology used in SE0X-LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

SE0X-LS supports BLE configure and wireless OTA update which make user easy to use.

SE0X-LS is powered by solar power + Li-ion battery , it is designed for long-term use up to several years..

Each SE0X-LS is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto connect after power on.
