The Dragino SE01 series is a 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, NB-IoT or CAT-M1 IoT Server.

It supports BLE congure and wireless OTA update which make user easy to use.

The Dragino SE01 is powered by 8500mAh Li-SOCI2 battery or solar panel with
li-on battery, it is designed for long-term use up to several years.
