SE01-NB NB-IoT Soil Moisture & EC Sensor
SE01-NB NB-IoT Soil Moisture & EC Sensor
The Dragino SE01-NB is an NB-IoT 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-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and support uplinks to various IoT Servers.
SE01-NB supports BLE configure and OTA update which make user easy to use.
SE01-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
SE01-NB has an optional built-in SIM card and default IoT server connection version. Which makes it work with a simple configuration.
