    SE02-LB LoRaWAN Soil Moisture & EC Sensor 2 Probes

    The Dragino SE02-LB is a LoRaWAN Soil Moisture & EC Sensor for IoT of Agriculture which has 2 sensor probes. It is designed to measure the soil moisture of saline-alkali soil and loamy soil. The soil sensor uses the FDR method to calculate the soil moisture with the compensation from soil temperature and conductivity. It also has been calibrated in the factory for Mineral soil type.

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

    The LoRa wireless technology used in SE02-LB allows the 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.

    SE02-LB supports BLE configure and wireless OTA update which make user easy to use.

    SE02-LB is powered by an 8500mAh Li-SOCI2 battery it is designed for long-term use up to 5 years.

    Each SE02-LB is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto-connect after power on.
