The Dragino SE01-LB/LS is a LoRaWAN Soil Moisture & EC Sensor for IoT of Agriculture. 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 SE01-LB/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.

SE01-LB/LS supports BLE configure and wireless OTA update which make user easy to use.

SE01-LB/LS is powered by 8500mAh Li-SOCI2 battery or solar powered + Li-ion battery it is designed for long term use up to 5 years.

Each SE01-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

Can I calibrate SE01-LB/LS to different soil types?

SE01-LB/LS is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at this link.
