The Dragino SE01-NB is a 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 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 NB-IoT IoT Server.
SE01-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, 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 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
SE01-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
Can I calibrate SE01-NB to different soil types?
SE01-NB is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at this link.
