Dragino SE0X-LB-LoRaWAN soil moisture and conductivity sensor

Dragino SE0X-LB is it soil moisture sensor and EC LoRaWAN for IoT agriculture that can be equipped 4 sensor probes . It is designed to measure soil moisture of saline-alkaline soil and loamy soil . The soil sensor uses the FDR method for calculating soil moisture with compensation for soil temperature and electrical conductivity. It has also been calibrated at the factory for the type of mineral soil.

He determines soil moisture, soil temperature and soil conductivity and uploads the values ​​wirelessly to the LoRaWAN IoT server.

The LoRa wireless technology used in the SE0X-LB allows the device to transmit data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption.

SE0X-LB psupports BLE configuration and wireless OTA update , which makes it easy for the user to use.

SE0X-LB is powered from a Li-SOCI2 battery with a capacity of 8500 mAh , designed for long-term use of up to several years.

Each SE0X-LB is pre-loaded with a set of unique LoRaWAN registration keys, register these keys to your local LoRaWAN server and it will connect automatically after power on.
