SE01 NB-IoT LTE CAT-M Waterproof Soil Moisture & EC Sensor

SE01 NB-IoT LTE CAT-M Waterproof Soil Moisture & EC Sensor

The Dragino SE01 is an NB-IoT LTE CAT-M 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 the compensation from soil temperature and conductivity. It also has 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 NB-IoT IoT Server.

SE01 supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and support uplinks to various IoT Servers.

SE01 supports BLE configure and OTA update which make user easy to use.

SE01 is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
