SE01-LS Solar Powered LoRaWAN Soil Moisture & EC Sensor Node

The SE01-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 the FDR method to calculate the soil moisture with compensation from soil temperature and conductivity. It has also been calibrated in the factory for Mineral soil type.

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

The LoRa wireless technology used in SE01-LS 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.

SE01-LS supports BLE configuration and wireless OTA update, which makes users easy to use.

SE01-LS is powered by a solar panel + Li-ion battery. It is designed for long-term use up to 5 years.

Each SE01-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.
